Summary: Add "compose" function to the functools

Initial Comment:
I think it would be very usefull to have something 
similar to Haskell's "dot" operator in Python, IMO it 
should be something like this (untested):

def compose(f, g):
    return lambda *args, **kws: f(g(*args, **kws))

but C-coded. So, _functools can be a good place for it.

If there's interest in this, I already have an implementation in my
functional package (http://cheeseshop.python.org/pypi/functional).
