You already are -- in fact, that is the only way this works.
(I'd wondered why nobody brought this error up in this discussion
before. Probably it wouldn't have been ugly enough.)

I don't see a significant speed difference between positional and keyword
arguments to format() when testing with two arguments.

Four shall be the number of spaces thou shalt indent, and the number of thy
indenting shall be four. Eight shalt thou not indent, nor either indent thou
two, excepting that thou then proceed to four. Tabs are right out.
