Re: [Boost-users] [boost] [type_erasure] Review started (July 18-27, 2012)

Hello, Just some questions: 1) Missing #include <cassert> in "boost\type_erasure\detail\storage.hpp" 2) Maybe i'm missing something, but it feels like the library doesn't support concept function arguments an return types that contain placeholder as a template parameter. Imagine a concept that returns "std::pair", where TIterator is another any: template struct foo_concept { typedef std::pair result_type; static result_type apply(C& c) { return std::make_pair(c.begin(),c.end()); } }; Probably the problem is with detail::rebind_placeholders_in_argument. The expected behavior is replacing 'TIterator' with something like 'std::_Vector_iterator' (or what it should be in specific case), just like mpl::lambda replaces its mpl::_N placeholders. Also I cannot just replace std::pair with another any - I'm trying to match the preexisting concepts. I've put an example into attachment.

5. Did you try to use the library? With what compiler? Did you have any problems?

MSVC 9.0

6. How much effort did you put into your evaluation? A glance? A quick reading? In-depth study?

Several hours.

7. Are you knowledgeable about the problem domain?

Almost no. -- ------------ Sergey Mitsyn.
