[Python-ideas] An identity dict

[Bill Janssen]

Denis, if you're going to post to python-ideas, would you mind taking
that biohazard symbol out of your user name?  My Emacs-based mail reader
thrashes for quite a while trying to find a glyph for it before it gives
up and renders it as a hollow rectangle.

I'd normally just add you to my kill-file, but I hate to give up on
python-ideas people that fast.  I'm sure you're not really a biohazard :-).
