Detailed Description

An implementation of std::any_cast, which uses type_info::hash_code to check validity of cast types.

This is required as Clang compares types as being equivalent based on their type_info pointer locations. These are not guaranteed to be the same with identical types linked in multiple targets from shared libraries. The current Clang implementation of type_info::hash_code is based on the type names, which should be consistent across translation units.
