I would disagree with any attempt to move the docstring away from
immediately next to the function in the source file.

You can currently do that if you insist, after all __doc__ is just an
ordinary attribute:

>>> def f():
.... pass
....
>>> f.__doc__ = some_other_text


I don't think we should do anything that *encourages* people to separate
the code and docstrings in the source file.

On the assumption that functions will continue to be written:

def f():
"""Doc string"""
pass


I like the proposal to make f.__doc__ a descriptor that lazily loads the
doc string from disk when needed, rather than keeping the string in
memory at all times. Whether this leads to enough memory savings to
justify it is an open question.
