Assuming I'm intuiting your question correctly, then you're incorrect;
they are "read/write". You just need a `nonlocal` declaration for the
variables in question. See http://www.python.org/dev/peps/pep-3104/
and http://docs.python.org/release/3.1.3/reference/simple_stmts.html#nonlocal
for details.

Cheers,
Chris
