Antonio Cuni demoed some great improvements to the pdb module at EuroPython. A project called pdb++

http://codespeak.net/svn/user/antocuni/hack/pdb.py Among its improvements it includes the ability to debug through generator frames, which pdb can't. It would be great to see some of these fixes folded back into the standard library version. +1

+1 on adding tracing through generators. Not so much about the other pdb++ features that were demoed.

While I liked the demo at EuroPython (and applauded), in general I am wary of adding this kind of UI cleverness to the stdlib -- things like the (seemingly curses-based) updating of the listing in-line are usually pretty fragile. Also the development cycle of a tool like this is likely 1-2 orders of magnitude over that of the stdlib. (For this reason I also think it's right that ipython is still a 3rd party tool).
