What I really want to be able to do is everything I can do in Haskell,
but in C++ :)  I'm very grateful for Boost.Lambda but language support
is needed to make it fully functional (pun not intended).

I like local functions, but one problem I see with this is that it can't
work in a template.  If you make f a template it will be ambiguous
without a cast or something.  If only we could pass functions by name.
