TODO (known issues):
- Create a full list of known issues.
- Check all the examples and ammend as needed.
- Update documentation to be consistent with examples.
- Identify other boost libraries using Phoenix in order to
  decide on priorities for fixing the bugs below.
    One such library is Boost log.
- Identify dependencies on other libraries and cooperate on bugs.
    It is now known that the other libraries which use Boost Phoenix
    are Boost Spirit and Boost Meta State Machine (MSM)
- Add more examples
- Develop documentation.
    A start has been made on this in release 3.1.0
- Inspection report outstanding issues

CHANGELOG

- DEVELOP

- Many of components now supports C++11 variadic templates.
  This is not a breaking change.

- Boost 1.59.0

- Support for <unordered_set> and <unordered_map>
  This involves the following changes.
  phoenix/config.hpp - New section with the following description:

  This section is to sort out whether hash types or unordered types
  are available. This depends on whether stdlib or libc++ is being used
  and also whether C++11 or C++03 is being used.

  Client code should contain this:

  #ifdef BOOST_PHOENIX_HAS_HASH
  #include BOOST_PHOENIX_HASH_SET_HEADER
  #include BOOST_PHOENIX_HASH_MAP_HEADER
  #endif

  #ifdef BOOST_PHOENIX_HAS_UNORDERED_SET_AND_MAP
  #define BOOST_PHOENIX_UNORDERED_SET_HEADER <unordered_set>
  #define BOOST_PHOENIX_UNORDERED_MAP_HEADER <unordered_map>
  #endif

  The client code can then chose the implementation provided.
  See the example in test/stl/querying_find2.cpp
  This example file has been adjusted for a problem with MSVC 10

  Modified files:
     phoenix/stl/algorithm/detail/has_find.hpp
  New files:
     phoenix/stl/algorithm/detail/is_unordered_set_or_map.hpp
     phoenix/stl/algorithm/detail/std_unordered_set_or_map_fwd.hpp
  New test file:
     phoenix/test/algorithm/querying_find2.cpp

  Support for retrieving the return type of boost::phoenix::function objects.
  This is needed in the lazy functionality.
  Modified file: boost/phoenix/function/function.hpp

  Revised version of lazy functionality with added functions.
  Modified files in boost/phoenix/function:
    lazy_operator.hpp lazy_prelude.hpp lazy_reuse.hpp
  New files:
    lazy_signature.hpp lazy_smart.hpp
  New test files:
    lazy_compose_tests.cpp lazy_fold_tests.cpp lazy_scan_tests.cpp

- Feature enhancements #5604 Sequenced statements of a catch_ statement is
  now able to handle thrown exception via local variables.

  Modified files:
    boost/phoenix/statement/try_catch.hpp
  Modified test files:
    exceptions.cpp

- V3.2.0 in Boost 1.58.0

- patch for #10927 in test/stdlib/cmath.cpp
- patch for #11085 in test/function/function_tests.cpp

- Bump version number to 3.2.0 in version.hpp.

- New header files in boost/phoenix/function
  These are the first versions of the lazy functionality being introduced.
  This is reimplementation of the ideas in FC++ on top of Phoenix.
  The Phoenix code used is Phoenix.Function, along with Boost.Function.
  lazy_prelude.hpp  This is the top level header and also has prelude functions.
  lazy_operator.hpp This defines lazy operators such as plus and minus.
  lazy_list.hpp     This defines list<T> a lazy list class and associated code.
  lazy_reuser.hpp   This defines the reuser functions used in the code.

- New tests for lazy functionality.
  test/include/function/lazy_headers Test of the header structure.
  test/function/lazy_list_tests      Simple tests of list<T>.
  test/function/lazy_list2_tests     More tests of list<T>.
- Develop documentation for version 3.2.0
  This includes a new section on the lazy list implementation.

- Fixed name clash by renaming 'at' to be 'at_' because the name 'at' is
  used in phoenix/stl/container/container.hpp.

- Fixed an unused typedef in phoenix/scope/let.hpp
  - contributed by Kohei Takahashi

- V3.1.1

- Bump version number to 3.1.1 in version.hpp and branch for release.

- New tests for lazy functions using existing phoenix/function capability.
  lazy_argument_tests, lazy_make_pair_tests, lazy_templated_struct_tests

- New example bind_goose.cpp comparing boost.bind and boost.phoenix.bind.

- Changes to let_tests and more_let_tests to avoid failing cases.

- Updates to documentation.

- V3.1.0
- Bump version number to 3.1.0 in version.hpp and branch for release.
- New file boost/phoenix/config.hpp to centralise configuration issues.
  At the moment it simply includes boost/config.hpp
- Changes to some tests to identify problems with several compilers.
- Add more cases to cmath test to test failures on some compilers.
- #7165 and #7166 Change tests to phoenix/core.hpp to reduce compiler load
- Testing fix for failures of tests as follows
  bind_member_function_tests, bind_mf2_test, bind_test
  with compilers including gcc 4.9.0 and clang 3.5
  This involves use of boost::lazy_disable_if to resolve
  the choice of overloaded bind functions in
  bind/bind_member_variable.hpp
  bind/bind_member_function.hpp Add reverse test boost::lazy_enable_if
  This resolves a smaller number of failures.
- #9742 New tests for_each and for_test to attempt to resolve this.
- bind_rv_sp_test changed to give workaround for MSVC 8,9,10,
  This removes a COMDAT error which does not occur with boost/bind.

- V3.0.6
- Fixed bug in example/container_actor.cpp in end() function.
- Fixed bug4853 and 5626 - added header <utility> for std::forward.
- Fixed bug4853 - added header <iostream> for gcc 4.9 test
- New Feature - boost::phoenix::display_expr(expr)
    In file boost/phoenix/core/debug.hpp
    and also included from boost/phoenix/core.hpp
    For now this drops through to the boost Proto version.
    I intend to add some more tags for better information.
    New test debug for the new header.
KNOWN BUG - WARNING
- New test more_let_tests to check for problems with losing temporary values.
    I think this is a serious problem which is affecting some compilers
    and not others. I have seen the problem with Clang 3.4 although not
    when run with C++11. These tests should find out where else there is a
    problem. At the moment these tests are passing.
    I now have cases which fail for Clang 3.4 with optimization -O2 but not
    without optimization. Under investigation.

- V3.0.5
- Documentation
    Start on fixing main documentation - whats new.
    Fixed reference for FC++ in two locations.
    Fixed example for nested let (#8564)
- Fixed #9113 warnings on -Wshadow
    Fixed all warnings
- Fixed #8298 Clang error with Boost Phoenix Local Name Assignment using C++11
    This is not expected to compile in the form supplied.
    Added test bug8298 to show correct operation.
    Added test bug8298f to show expected failure.
- Fixed #7730 Generic specializations of is_nullary for custom terminals
    are not possible
    Fix to specialize custom terminals is now set as a default.
    Define BOOST_PHOENIX_NO_SPECIALIZE_CUSTOM_TERMINAL not to use this.
    Test bug7730 tests the not use case.

- V3.0.4
- Inspection report outstanding issues
    Fixed copyright and licence in preprocessed files for function_equal
- boost/phoenix/version.hpp Added BOOST_PHOENIX_VERSION_NUMBER
    when boost/predef is available.
- Fixed tabs in ChangeLog!!
- Fixed #9295 PHOENIX_LIMIT macro clash: property_tree -- log/sink
    This will not show up in phoenix - used in spirit/classic
- Fixed #8704 Using Phoenix lambdas on top of custom Proto expressions
    This works for C++11 only.
    Test cmath applies to this.
- Fixed #7624 Deduction failure
    This works for C++11 and has a workaround for C++03
    Test bug7624 tests both versions.
- Fixed #7166 Phoenix unconditionally sets BOOST_PROTO_MAX_ARITY
    using patch supplied
    Added test bug7166
- Fixed #7165 cannot change BOOST_PHOENIX_LIMIT
    using patch supplied

    Added test bug5715

- V3.0.1
- Started CHANGELOG
- Fixed bug_000008 to use phoenix headers correctly.
    This fixes it for most systems but not for
    Clang Linux C++11 with libstdc++ where the problem seems
    to be in boost/thread.
    Clang Linux C++11 with libc++ works.
- Fixed #9113 warnings on -Wshadow (some fixed)
- Fixed #9111 unused parameter warning in phoenix bind
- Fixed #8417 Minor documentation

    Fixed copyright and licence issues
    Fixed tabs in some files
    Deleted some empty unused files
