We use ret=5 in the test suite to say "unset this variable, but it's OK if
it wasn't set in the first place" but still fail on error. The only
other one I can imagine that would be useful is "you tried to get a
variable but it did not exist, and there was no other error". Which is
probably what ret=1 is attempting to do, though it also encompasses
syntactically bogus keys.
