[Python-ideas] Make partial a built-in

[Stephan Houben]

I must admit I am a bit partial to partial, you can do fun things like this:

>>> from functools import partial
>>> @partial(partial, partial)
... def add(x, y):
...     return x+y
...
>>> add(3)(4)
7

I suppose that isn't exactly going to convince Guide to put it in builtins,
though.
