For me, the problem with that proposal is not the precise format syntax, but the fact that formatting is tied to a specific function which also outputs stuff to screen.

So borrow a trick from Common Lisp and use a destination of None to mean "return the formatted text as a string".

>>> x = printf("$2 $1", 123,321)
321 123
>>> print x
None
>>> x = printf("$2 $1", 123,321, to=None)
>>> print x
321 123

Or is that too cryptic?
