Ok, just been teaching myself about tie, and thought I was getting the hang of it, so I built myself two things:

1. Stopwatch.pm
This module has, surprisingly, four methods. No prizes for guessing what they're called!
Now then, each sub in Stopwatch contains a print statement along the lines of: print ("Inside Stopwatch::TIESCALAR"); so I know which sub is being executed.

2. go.pl, in its entirety, is here: 
use Stopwatch;
print "Just executed use\n";

tie $s, 'Stopwatch';
print "Just executed tie\n";

$s = 0;
print "Just executed \$s = 0;\n";

print "$s\n";
print "Just executed print \$s\n";

$s = undef;
print "Just executed undef\n";

So what? I hear you cry...
Well, all's well untill the print "$s\n"; statement. It calls Stopwatch::FETCH twice in a row. Why??? For some reason this small 'feature' is really getting under my skin, any explanations very welcome!


advTHANKSvance,
