Re use warnings rather than use strict - thanks for the correction.

Likewise, you are right about the "0100" not being equal to 100, which is what I meant about being sure that the values are represented internally as numbers.

So if you said:

 $a = "01000";
 $b = 1000;
 print $a eq $b ? 1 : 0;
 > 0
 $a=$a+0;
 print $a eq $b ? 1 : 0;
 > 1
