Re^2: Seeking guidance on getting better at Perl.

[kcott]

While the diagnostics pragma is a useful tool for debugging, particularly when you are learning Perl, I would recommend removing, or commenting out, the use diagnostics; line in production code.

Perhaps, as a general rule-of-thumb, consider doing this at the same time that you change

$DEBUG_MODE = 1;

to

$DEBUG_MODE = 0;

and for much the same reasons.
