Yeah, I'm afraid so. I'm pretty sure I recall cases where people
invoked I/O functions by name, and I definitely recall cases where
operator-implementation functions were invoked by name. Those might
not be very bright things to do, but people do 'em.
We'd also be risking creating problems for individual apps by conflicting
with user-defined functions that we didn't use to conflict with. We take
that chance every time we add functionality, of course, but usually we can
soothe complaints by pointing out that they got some new functionality in
return. I don't think "we made I/O function names more uniform" is going
to be a very satisfactory excuse for breakage.
