As far as the problem the library solves goes,
TypeErasure is a generalization of several
existing components:

Boost.Any:

Boost.Function:
any<mpl::vector<copy_constructible<>, typeid_<>, callable<void(int)> > >

AnyIterator:

I expect that the majority of uses of the
library will be about this level of complexity.
