[Python-Dev] Speeding up CPython 5-10%

[Yury Selivanov]

BTW, this optimization also makes some old optimization tricks obsolete.

1. No need to write 'def func(len=len)'.  Globals lookups will be fast.

2. No need to save bound methods:

obj = []
obj_append = obj.append
for _ in range(10**6):
    obj_append(something)

This hand-optimized code would only be marginally faster, because of 
LOAD_METHOD and how it's cached.
