[boost] [python] type_id

I see that the implementation of type_id is chock full of special code. There appears to be so much difference between how compilers handle stuff (the shared lib problem documented in the header is especially disturbing). However, this does not seem to be isolated just to using Boost.Python, so is it possible to have it moved somewhere else more common, like boost/type_id.hpp or something similar which makes it more widely available? Thanks!
