package subs;
our $VERSION = '1.00';
=head1 NAME
subs - Perl pragma to predeclare sub names
=head1 SYNOPSIS
use subs qw(frob);
frob 3..10;
=head1 DESCRIPTION
This will predeclare all the subroutine whose names are
in the list, allowing you to use them without parentheses
even before they're declared.
Unlike pragmas that affect the C<$^H> hints variable, the C<use vars> and
C<use subs> declarations are not BLOCK-scoped. They are thus effective
for the entire file in which they appear. You may not rescind such
declarations with C<no vars> or C<no subs>.
See L<perlmodlib/Pragmatic Modules> and L<strict/strict subs>.
