      my $a : watch;
    • I'm mostly playing with the "non-intrusive" Idea,
      I mean look at the following code :

      #use MyDebug; my $a;#!watch($a)! for my $i (1..10) { $a*=$i; } print $a;
      This is perfectly valid code.
      Now If I uncomment the 'use Mydebug;' line it will alsos works,

          I clearly emphazized the later...

          BTW: What would be your proposition for this module's name ?
