in thread looking for a good idiom: return this if this is true
Given how often I hear about (even experienced) programmers mistakenly typing "=" in an if statement when they meant "==", I don't know if encouraging this particular idiom as a rare case where it is indeed what you mean is a good idea. Might I suggest this instead:
while (my $result = thatroutine()) { return $result; }
As an aside, I was actually surprised that the version with if didn't warn about the single "=", but a little testing showed that the warning only appears to happen if you mistakenly assign (instead of compare) a literal value, not a subroutine.
