Not sure offhand, though I could see how it might be useful. A use-case
might be that you have a variable template string which is user defined,
where they can choose from the arguments that are passed which ones they
want displayed and how. Otherwise, you'd have to have a bunch of
different call sites to format() depending on which options are
requested.
I'd go look at what C sprintf() does, as I feel like that's what we're
trying to emulate and see what it does.
There is also a patch that I reviewed/commented on about changing format
around a bit. I'm guessing it needs more review/work, just havn't
gotten back around to it yet.
Thanks,
Stephen
