I have a co-worker who is a long-time C coder. He showed me a trick that I should have thought of a long time ago, but never occurred to me.

I use it often now and it simplifies things greatly.

At the head of a script, I add the line: 

my $DEBUG = 1;

[download]

and after a variable should gain a new value, I add: 

print $variable if $DEBUG;

[download]

This helps me make sure my variables are given the values that I want. When I want the text to run without the extra mess, I change $DEBUG to 0.

Anyone else have any neat practices that keep them honest, besides using 'strict' or '-w'?
