Yeah, right. Although that's not quite the same, is it?

Say I have an existing project and want to start using Typeof. There might me a
lot of already-written source code and I'd have to change all the includes therein
that refer to the libraries I want Typeof support for.
As an end user, I would definitely prefer changing my include directory over
changing all the includes (especially considering your own point that the Typeof
library is only a temporary solution).

The situation becomes even more delicate if I use a library that in turn uses a
some part of Boost. Now I can either go through the foreign code and figure out
what needs to be included or include Typeof support for the whole part of Boost my
library depends on.
