it's easy to make up examples, but
i've never seen this in practice.
if you're writing the print statement,
you *know* which function you're in.
it's only useful inside macros,
which are mostly deprecated.

it would often be useful to be able to
format a given pc as a function name
for use in prints about your caller,
but that's a whole different can of worms.
