=head1 NAME
warnings::illegalproto - Disable illegal prototype warnings on old Perls
=head1 VERSION
version 0.001003
=head1 SYNOPSIS
use strictures 1;
use signatures;
no warnings::illegalproto;
sub ($foo) { ... }
=head1 DESCRIPTION
This module was implemented so that people can C<< use strictures >> and
C<< use signatures >> at the same time. Thanks to mst, in Perl 5.12 and
greater this is trivial, but before that a strange dance had to be done.
This module will do the right thing for both before and after 5.12, but if you
want to use the native 5.12 and greater without this module, feel free to cargo
cult the following:
no if $[ >= 5.012, warnings => 'illegalproto';
no if $[ < 5.012, 'warnings::illegalproto';
