Yep, I'm sure there are plenty of people in that situation. I suspect
it's been used heavily in places where a (C) function require an
integer argument, i.e. (foo (inexact->exact (round x))). Though as
long as (inexact->exact (round x)) is guaranteed to return an integer,
perhaps that's sufficient.
