=head1 NAME

Perl::Critic::Policy::Subroutines::ProhibitSubroutinePrototypes - Don't write C<sub my_function (@@) {}>.

=head1 AFFILIATION

This Policy is part of the core L<Perl::Critic|Perl::Critic>
distribution.


=head1 DESCRIPTION

Contrary to common belief, subroutine prototypes do not enable
compile-time checks for proper arguments.  Don't use them.


=head1 CONFIGURATION

This Policy is not configurable except for the standard options.
