This has already been fixed in CVS, so don't worry. Another user sent me a
patch when 2.4a1 came out.

I've discussed this a lot on the massive thread on this topic which took place
in python-dev. Look in the python-dev archives for my name, if you are
curious about the arguments I presented.
Right now, I'm going to wait for Guido to settle on a syntax before I make
decisions about ipython. There's still a chance he might go for something
other than @, case in which I won't have to do anything.
If @ becomes official python syntax, then I'll solicit feedback from the
ipython community on what to do. I'll remember your suggestion, but please
keep in mind to repost it when the time comes, if we need to make changes.

Good to know, thanks for the report.
