I think the Egg library is awesome. Is it in the review queue yet?
If not, it should be. My opinion here is that it can co-exist with
the Forward library just as boost.bind can coexist with boost.lambda.
It's not always a matter of which is more sophisticated. Certainly,
bind is a subset of lambda. Yet, even with the simplicity of bind,
it is sufficiently useful in many applications. I'd say the same for
Egg and Boost.Functional.

Let's have more FP in C++! :-)
