NAME
Perl::Critic::Policy::Freenode::WarningsSwitch - Scripts should not use the -w switch on the shebang line
DESCRIPTION
The -w switch enables warnings globally in a perl program, including for any modules that did not explicitly enable or disable any warnings. The -W switch enables warnings even for modules that explicitly disabled them. The primary issue with this is enabling warnings for code that you did not write. Some of these modules may not be designed to run with warnings enabled, but still work fine. Instead, use warnings within your own code only.
#!/usr/bin/perl -w # not ok

This policy is part of Perl::Critic::Freenode.
