For this reason I would advocate omission of += and -= from the language. The problem is not that the behavior is inconsistent or that it breaks any -rules-, per se. The problem is that the behavior is non-intuitive and not just in a difficult-to-guess-at way, but in a can-directly-confuse-users way. Yes, $fqdn is potentially different from $::fqdn but if we're trying to guide people into a mindset of "variables are immutable" we should not muddy the waters with syntax that looks contradictory to that paradigm - especially if all it gains us is saving a few characters being typed. I believe this constitutes a compelling design reason to remove += and -=. ~Reid -- You received this message because you are subscribed to the Google Groups "Puppet Developers" group.
