G'day curiousmonk,

Your question appears to have been answered in the responses you've already received. I might just point out that $a and $b were poor choices for your examples as they're special variables that don't require declaration. Here's an excerpt from perlvar:

  • $a
  • $b
    Special package variables ... Because of this specialness $a and $b don't need to be declared (using use vars, or our()) even when using the strict 'vars' pragma. ...
