[section:is_complete is_complete]

   template <class T>
   struct is_complete : public __tof {};
  
__inherit If `T` is a complete type then inherits from __true_type, 
otherwise inherits from __false_type.

[important This trait is designed for one use only: to trigger a hard error (via a `static_assert`) when a template
is accidentally instantiated on an incomplete type.  Any other use case will cause ODR violations as the "completeness"
of type `T` may vary at different points in the current translation unit, as well as across translations units.
['[*In particular this trait should never ever be used to change code paths depending on the completeness of a type]].]

__header ` #include <boost/type_traits/is_complete.hpp>` or ` #include <boost/type_traits.hpp>`

__compat Requires C++11 SFINAE-expressions to function fully.  The macro `BOOST_TT_HAS_WORKING_IS_COMPLETE` is defined
when the trait is fully functional.
