What are your thoughts on adding a str.formatfrommapping (or similar name, maybe the suggested "formatmap") to 3.2? See http://bugs.python.org/issue6081 . This method would be similar to "%(foo)s %(bar)s" % d, where d is a dict (or rather any mapping object), but of course would use str.format syntax: "{foo} {bar}".formatfrommapping(d).
I like the idea. It's particularly handy when converting from %-formatting. Eric.
I've updated the issue with tests, minimal docs, and a name change to str.format_map. Having heard no objections and some support, I'll commit this shortly.
