- // This test was added due to a report that the Range Adaptors:
- // 1. Caused havoc when using namespace boost::adaptors was used
- // 2. Did not work with non-member functions
- // 3. The strided adaptor could not be composed with sliced
- //
- // None of these issues could be reproduced on GCC 4.4, but this
- // work makes for useful additional test coverage since this
- // uses chaining of adaptors and non-member functions whereas
- // most of the tests avoid this use case.
