(I think yes) It should be a hard error, generating an exception, not a warning. >Another question is: which is the earliest Perl version >should we target? Depends on the target audience. You shouldn't go to extra effort to support anything earlier than around 5.12 unless you have a specific user who can't upgrade Perl. Targeting earlier than 5.6 is a pain because the "our" keyword isn't available earlier. Personally I routinely test my CPAN modules against almost all versions back to 5.6.1, but I'm unusual in that regard. -zefram
