Fortunately, you'd still be able to do so in pre-5.10 perl. :-) Making reference stringification a warning wouldn't stop quick and dirty debugging, which is why I say that would, at a minimum, be an improvement on the current situation. I might be in favor of refaddr() moving into core from Scalar::Util so it's always available even if module loading is borked. -- DavidThread Previous | Thread Next
