=head1 NAME
|
|
|
|
subs - Perl pragma to predeclare subroutine names
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
use subs qw(frob);
|
|
frob 3..10;
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
This will predeclare all the subroutines whose names are
|
|
in the list, allowing you to use them without parentheses (as list operators)
|
|
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 lexically scoped to the block they appear
|
|
in: they affect
|
|
the entire package in which they appear. It is not possible to rescind these
|
|
declarations with C<no vars> or C<no subs>.
|
|
|
|
See L<perlmodlib/Pragmatic Modules> and L<strict/strict subs>.
