I am strongly against the broad expansion of this module 
until it has lived for some time as a successful, mature, 
well-loved stand-alone module.

Each addition needs to be fully thought-out in terms of 
use cases and evaluated for clarity/efficacy against 
existing Python solutions.

At some point, there was a substantial discussion on just 
the compose() function.  While it seems basic to 
functional programming, it was found not to be necessary, 
and not represent much of an improvement over a simple 
lambda expression.  Also, a number of folks have 
difficulty remembering whether compose(f,g) means f(g(x)) 
or g(f(x)).

Also, some of these entries duplicate those in the 
itertools module.  It is not in Python's best interests to 
provide several ways of doing the same thing.
