Request for useful functions on dicts

[Leif]

Hi, everybody. I am trying to collect all the functions I've found useful for working with dicts into a library:

https://github.com/leifp/dictutil

If you have a favorite dict-related func / class, or know of similar projects, please let me know (or open an issue on github). Bear in mind that the functions don't even have to come from python; if you have a favorite PHP / APL / COBOL / etc associative array function, that's fair game.

Thanks,
Leif

P. S.  I'm participating in Julython [ http://www.julython.org/ ], and it's fun.  You should all join and show everyone that your city has the most open source python activity.
