Re: perl 5.005_03 woes

the_slycer,
In addition to the proper de-referencing that liz illustrates, you are using $a as an unscoped global. You should avoid using $a and $b as variable names as they are used by Perl for sorting. See perldoc -f sort. It should then be properly scoped with my or *gasp* our if you really need it to be global.

If my memory serves me correctly, couple of things to be aware of:
• 5.005.03 doesn't do "our"; use use vars instead
• 5.005.03 doesn't do like use warnings; use /my/perl -w instead

Yah, I knew/know the $a/$b bit actually (should have thought before posting), I never use either in production code. Was just making it simple for someone that was testing it for me. I always use warnings; use strict; (there was another "forgotten" surprise from that btw :) ).

the_slycer,
Actually I assumed you did have:

#!/usr/bin/perl -w
use strict;

In the small snippet you showed on 5.6.1 you would not have encountered any problems. That is why I didn't specifically mention them. This is because the strict pragma ignores $a and $b since Perl uses them to allow you to build a custom sort routine.
