Assume I have the following function template:

template <typename Container> typename Container::value_type get_front(const Container& c) { return c.front(); }

Is there a way I can force type_erasure::any<> to have a `value_type` typedef? I can create a concept which requires the underlying type to have it, but I'd like to make `any` to have such a typedef.

Specialize concept_interface. See http://www.boost.org/doc/html/boost_typeerasure/concept.html#boost_typeerasu... and http://www.boost.org/doc/html/boost/type_erasure/concept_interface.html In Christ, Steven Watanabe
