The property shouldn't care, it got the getter code object before the
name disappeared. As for users, we can add a first step of:
rename .foo() -> getFoo()
foo = getFoo
so users won't have to change their servlets until the properties are
ready.

I mean, how you were going to transform foo/setFoo into properties:
what all the existing pieces would morph into. If not the way I
described, then how?

True, but doing it piecemeal would help to control for errors at
each stage. Also, how often do people actually use the docstring
objects anyway, rather than reading them in the source? Anyway,
we can make quick-and-dirty docstrings thus:
doc = "GET SYNTAX:\n%s\n---\nSET SYNTAX:\n%s" % \
(getFoo.__doc__, setFoo.__doc)
foo = property(getFoo, setFoo, none, doc)
for now and pretty it up later.
