Hi,

I reached for Boost.TypeIndex the other day expecting to find a kind of
dynamic_cast I could use in the absence of Rtti. I didn't find it, so I
wrote something to emulate it using type_index internally.

It's working, but before I go too far and clean this up and possibly submit
a pull request, I would like to gauge if there's interest in such a thing
or if there's some fundamental reason why it doesn't exist.

So, thoughts?

Thanks,
