[Python-Dev] str.format_from_mapping

What are your thoughts on adding a str.format_from_mapping (or similar 
name, maybe the suggested "format_map") 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} 

I like the idea. It's particularly handy when converting from %-formatting.
