I know this is a pretty stupid question, maybe, but is it better to
use strict? I have never gotten a concise answer to this question
because there reallty isn't any docs on it.
thanks,

% perldoc strict

strict - Perl pragma to restrict unsafe constructs

SYNOPSIS
use strict;

use strict "vars";

You have a strange meaning of "isn't any". Care to elaborate?

print "Just another Perl hacker,"; # the original

There are a number of good reasons to use strict, however, in my case
I use it to help in de-bugging and all other side benefits are a
bonus.

90% of my errors are misspelt variables, IE, somwhere you have

# my $blah;

and later you use $blaj by mistake, it will tell you in its own
fashion that $blaj is perhaps a mistake.

Try this program to get get a message that would not be generated if
'use strict' was not used;

=========================

#!/usr/bin/perl

use strict;

my $blah;

$blaj =2;

========================

You should also 'use warnings' as well. They all help

Yes. I try to make all my (multi-line) programs start

#!/usr/bin/perl
use strict;
use warnings;

The subject is discussed in this newsgroup surprisingly often.

There seems to be a strong consensus for strict and warnings. There is a
respected minority (possibly just one) who argue that `-w` is better
than `use warnings`. Unless you have read and understood the discussion
(and how it applies to your current project) you should 'use warnings'.

I like it because it makes me be constantly aware of scope since I
have to consciously define everything somewhere. That can only help as
your program code gets longer.
