[Python-Dev] functools.compose to chain functions together

I was tricked into reading it different when used with getters, i.e.

  l.sort(key=compose(attrgetter('name'),attrgetter('age')))

is too easy (IMO) to read as applying foo.name.age on all elements of
the list.

It's best to search for "compose" in the bug tracker:
