[boost] RFC: type erasure

AMDG Over the last few months I've re-done my type erasure library from scratch, fixing a lot of the bad design decisions I made originally. Here's a basic sample of what you can do with it: simulate boost::any: type_erasure::any< mpl::vector<copy_constructible<>, typeid_<> > > x(10); simulate boost::function<void(int)>: type_erasure::any< mpl::vector<copy_constructible<>, typeid_<>, callable<void(int)> > > f(foo); The code is available from the Vault: http://tinyurl.com/3z9jcwp The library is nearly complete. I've included pre-built html documentation in the zip. Questions, comments, and criticism are welcome. In Christ, Steven Watanabe
