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 must be missing something, but what's the difference with XXX.format(**d)?
It allows arbitrary mappings.
