I seldom have to read C code aloud, and the ?: operator is
rare-ish; but I would suggest reading a?b:c as "a chooses b else c"
or (shaving a syllable) "a gives b else c" or something like that.
Or, ploddingly but unambiguously, "a query b colon c".

I can't imagine *actually* reading it as if "foo" were the
condition. But I can imagine reading it, to begin with, as if
it were a Perlish conditionalized statement: "(return foo) if
bar else ... aw heck, that can't be right". Which is probably
benign but slows down comprehension.
