[Python-ideas] Syntactic sugar to declare partial functions

[Michel Desmoulin]

I'd rather have functools.partial() to be added as a new method on
function objects.

Would become:

add_2 = add.partial(2)

Nothing to change on the parser, no obscure syntax for future readers,
and we can get the opportunity of rewriting partial() in C as right now
it is amazingly way, way slower than a lambda.
