NAME

       Perl::Critic::Policy::Community::Prototypes - Don't use function prototypes

DESCRIPTION

       Function prototypes are primarily a hint to the Perl parser for parsing the function's
       argument list. They are not a way to validate or count the arguments passed to the
       function, and will cause confusion if used this way. Often, the prototype can simply be
       left out, but see "Signatures" in perlsub for a more modern method of declaring arguments.

         sub foo ($$) { ... } # not ok
         sub foo { ... }      # ok
         use feature 'signatures'; sub foo ($bar, $baz) { ... }      # ok
         use experimental 'signatures'; sub foo ($bar, $baz) { ... } # ok

       This policy is similar to the core policy
       Perl::Critic::Policy::Subroutines::ProhibitSubroutinePrototypes, but additionally ignores
       files using the "signatures" feature (which is also enabled by a "use" declaration of perl
       version 5.36 or higher), and allows empty prototypes and prototypes containing "&", as
       these are often useful for structural behavior.

AFFILIATION

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

CONFIGURATION

       This policy can be configured to recognize additional modules as enabling the "signatures"
       feature, by putting an entry in a ".perlcriticrc" file like this:

         [Community::Prototypes]
         signature_enablers = MyApp::Base
