My string.Formatter subclass (attached to this bug report) does do this:
$ ./python.exe
Python 2.7a0 (trunk:69516, Feb 11 2009, 14:30:31)
[GCC 4.0.1 (Apple Inc. build 5465)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> from auto_number_formatter_1 import MyFormatter
>>> f = MyFormatter()
>>> f.format('{} {} {}', 3, 'pi', 3.14)
'3 pi 3.14'
>>>
This is just for vetting the concept, if it's accepted I'll modify
''.format(). It's not a huge change. I just want to make sure that this
implements what people are expecting.
The talk about '{:d}' and the like is just to make sure all the cases
are addressed. I doubt it would often be used that way.

Agreed.
