Cool! 

I think that effort must concentrate more on:

1) using map and fold instead of iterators to implement algorithms.
    In most FP languages I know, these higher order functions are 
    the most used all over the place.
2) the porting of fold and map (is there a map?) to less conformant
compilers.

3) OK, just my personal wish: Use more FP sounding names. This is 
all about FP, no more, no less. Pattern matching, recursion,
higher order functions, fold, map, curry, lambda, the list goes on...
Clearly, the STL authors are knowledgable with FP. STL is a good
start in introducing FP (stealthily) to the C++ programmer. It is
my opinion that we should extend that further. Why do we seem to
underestimate the C++ programmer. C++ programmers are the
**BEST* in the world (Period :-).
