Functional Programming in Python [pdf]

For compose to really shine, you need to be able to curry/partially apply functions. This part of things is made much more difficult than necessary because of Python's unnecessarily neutered lambda syntax (in fact, I don't think one can claim that Python is FP friendly until this decision is corrected).

It's also worth noting that reduce() was removed as a builtin for Python 3.

I'd love let-like syntax in lambdas, something along the lines of

    lambda x: f(y) + g(y) for y = expensive_computation(x)

In Python 3, `reduce` can be trivially imported from `functools`.

The ugly hack around this would be

    lambda x: (lambda y: f(y) + g(y))(expensive_computation(x))

It's possible to hack currying into python with a decorator like:

(I made this for fun, use at your own risk)
