I've been wondering whether it's possible to perform a similar analysis on non-mapping-type format strings, so as to know how long a tuple to provide,
I just tried an experiment, and it doesn't seem to be possible.
The problem seems to be that it expects the arguments to be in the form of a tuple, and if you give it something else, it wraps it up in a 1-element tuple and uses that instead.
This seems to happen even with a custom subclass of tuple, so it must be doing an exact type check.
So it looks like you'll have to parse the format string.
