A little of that is a good thing (IMO). The alternative is that we
explicitly declare each variable's semantics, which makes for a much
more wordy language.

I believe that we should think of assignments to __xxx__ attributes as
not being part of the function's body, but instead part of its
declaration, just as we do with its docstring.
"""This describe's foo."""
__author__ = 'Paul Morrow'
__version__ = '0.1'
__features__ = synchronized, memoized
# Everything above here is declaration.
# Everything below here is in the body.
pi = 3.14
return pi * diameter
