Re: On Commenting Out 'use strict;'

If I had been there, the conversation would have gone something like this.

name used only once

You are either putting data into a variable and not getting it out again (which seems pointless) or trying to get data out of a variable that you haven't put data into (which seems stupid).

global symbol requires package reference, things like that

Your code has variables that can be (accidently!) used outside of the necessary scope. This is dangerous.

It cluttered up the SYSOUT and made it hard to find the real bugs

This are the real bugs. Fix them.

Accidently

$var = "whatever";
sub foo {
    ...
    while ($var = <HANDLE>) {
        ...
    }
    ...
}
sub bar {
    ...
    foo();
    ... code assuming $var is unmodified ...
}

use strict;

my

$var

use strict

What does solve the problem is declaring a lexical variable my $var, or a local value local $var inside foo(), neither of which actually requires use strict.

use strict is a tool. It ain't no magical bullet.
