As a rule, I use two of them in every script (strict and warnings), 'diagnostics' when developing / debugging but I drop it for production code. Sure, it might be more comfortable to code without them, but sooner or later you'll miss a typo that has a nasty side effect. Some warnings may be ignored (such as "uninitialized value in concatenation"), except that they might clutter your output/log and distract from any serious message.


I've got a couple other tips:
  • Use perl -c occasionally. It won't run your script, but check the syntax. Good to catch any missing semi-colons.
  • Use perltidy on your code to make it easier to read. Does a syntax check, too.
  • Occasionally, run perlcritic for some best practices.

Perl::Critic::Policy::CodeLayout::RequireTidyCode(3pm)	User Contributed Perl Documentation Perl::Critic::Policy::CodeLayout::RequireTidyCode(3pm)

NAME
Perl::Critic::Policy::CodeLayout::RequireTidyCode - Must run code through perltidy. AFFILIATION
This Policy is part of the core Perl::Critic distribution. DESCRIPTION
Conway does make specific recommendations for whitespace and curly-braces in your code, but the most important thing is to adopt a consistent layout, regardless of the specifics. And the easiest way to do that is to use Perl::Tidy. This policy will complain if you're code hasn't been run through Perl::Tidy. CONFIGURATION
This policy can be configured to tell Perl::Tidy to use a particular perltidyrc file or no configuration at all. By default, Perl::Tidy is told to look in its default location for configuration. Perl::Critic can be told to tell Perl::Tidy to use a specific configuration file by putting an entry in a .perlcriticrc file like this: [CodeLayout::RequireTidyCode] perltidyrc = /usr/share/perltidy.conf As a special case, setting "perltidyrc" to the empty string tells Perl::Tidy not to load any configuration file at all and just use Perl::Tidy's own default style. [CodeLayout::RequireTidyCode] perltidyrc = SEE ALSO
