Fair enough; but her signature block still said that her Web host was on 5.8.8 when she posted the question and she did not clarify here until after we had had that discussion.
While our questioner may no longer need to be concerned about that detail, the issue is still a concern for module authors (and really only module authors — scripts can simply avoid aliasing $_ to read-only values when calling such "sensitive" routines) targeting backwards compatibility to perl versions before 5.14, and the workaround works in later versions, albeit with the caveat that you must collect your arguments into lexicals before localizing *_ or only use them again after exiting the block in which *_ was localized. I generally use the my $foo = shift; my $bar = shift; idiom to convert arguments to independent variables instead of leaving them as aliases, so localizing *_ is not a problem — @_ is empty well before that point.
