Not directly relavent to the PEP, but... Guido van Rossum writes:

Q. What about code compiled by the codeop module?

A. Alas, this will always use the default semantics (set by the -D command line option). This is a general problem with the future statement; PEP 236[4] lists it as an unresolved problem. You could have your own clone of codeop.py that includes a future division statement, but that's not a general solution.

Did you look at my Nasty Hack(tm) to bodge around this? It's at http://starship.python.net/crew/mwh/hacks/codeop-hack.diff if you haven't. I'm not sure it will work with what you're planning for division, but it works for generators (and worked for nested scopes when that was relavent). There are a host of saner ways round this, of course - like adding an optional "flags" argument to compile, for instance. Cheers, M. -- ARTHUR: Why should a rock hum?
