What should happen for:
def f():
if random.random() < 0.5:
a = 1
b = 2
else:
b = 1
a = 2
return locals()
? Right now co_varnames preserves the order that names were encountered when
compiling, so it'd be easy to make 'a' come before 'b' in locals(), so the
above function returns either {'a': 1, 'b': 2} or {'a': 2, 'b': 1}.
If we want to preserve the illusion that local variables are entries in the
locals() dict, though, then the dict ought to be either {'a': 1, 'b': 2}, {'b':
1, 'a': 2}. Making this happen would require extra machinery for an extreme
edge case so I'm guessing it's not worth it though.
