in reply to using 'my'

Can you spot the error?
$illusion = ''; print "$i11usion\n";
If you run this, you get: a new line.

However, if you use strict (and -w) you would know exactly what the problem is. Whether a program is 2 pages or 200 pages long, I'd rather not pull my hair out over such a trivial typo. But, there is always more than one way to do it - caveat programre!
