I'd just like to echo that this functionality is awesome. Heck, I
already have two past use cases in mind, let alone what is now possible.
Maybe if we hobble along doing this kind of research and practical work
enough, C++ will get real meta-programming in 20-something. Although the
monomorphic lambdas in C++0x do dampen the enthusiasm a bit...

My heartfelt thanks to all Boost library authors, in particular from
Boost.Bind to the Proto rewrite. Your work makes the life of thousands
of programmers better and keeps C++ interesting and useful.
