Sorry, that was just a mireading on my part.

Not insisting on anything, and not critical -- just wasn't immediately
obvious that was the only reason, and I've seen the numbers.c code be
fairly particular in the past.  But after looking up scm_to_mpz's code
too, I can of course see that it's "not much difference".

Sure.  I was commenting on a possible naming convention, not visibility.
As mentioned, I wondered if we have a policy of avoiding scm_* for
functions that areen't part of the public api, reserving that as a
signal.  Not sure, was just asking.

I wasn't either -- hence wondering about trying to compile with a
non-integral type if it were easy enough to be sure.  May not be a
problem at all.

Well, for what it's worth, I was hesitant too, but people asked me to
post my (as I told them) cursory comments.  I won't plan to pursue it
further.
