=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>.
