[Python-Dev] Add a frozendict builtin type

There are some alternatives to code.google.com, though. For example:

http://www.koders.com/default.aspx?s=frozenset&submit=Search&la=Python&li=*

>From a cursory look: quite a bit of the found results are from the various
Python implementations, and there is some duplication of projects, but it
would be unfair to conclude that frozenset is not being used since many of
the results do look legitimate. This is not to argue in favor or against
frozendict, just stating that there's still a way to search code online :)
