The use strict in subroutines is real nice at telling me variables that have not been specified properly.

It doesn't seem to say anything about extra specifications of variables that are not used in the routine. This makes it harder to make sure everything is "clean". Generally this happens after you write the routine and then make changes later. You forget to go remove the "my $vars".

It would be nice if the compiler would let us know about them.

This motion for an enhancement to 'strict' has failed to receive a second in more than twelve years. I recommend that the ticket be closed.

Thank you very much. Jim Keenan

Is this is asking for Perl to detect variables declared but not used?

That might be difficult for certain cases and possible in others.

But I can hardly see making it a fatal compilation error in the default case. Perhaps it could be a warning at best.

I believe this is a duplicate of https://rt-archive.perl.org/perl5/Ticket/Display.html?id=5087

A year-and-a-half later\, this feature request still has not received a second. Marking ticket rejected.
