NAME
Perl::Critic::Policy::Freenode::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, and allows empty prototypes and prototypes containing &
, as these are often useful for structural behavior.
AFFILIATION
This policy is part of Perl::Critic::Freenode.
CONFIGURATION
This policy is not configurable except for the standard options.
