---|
5 | subs - Perl pragma to predeclare sub names |
---|

7 | =head1 SYNOPSIS |
---|
8 | |
---|
9 | use subs qw(frob); |
---|
10 | frob 3..10; |
---|

---|
12 | =head1 DESCRIPTION |
---|
13 | |
---|
14 | This will predeclare all the subroutine whose names are |
---|
15 | in the list, allowing you to use them without parentheses |
---|
16 | even before they're declared. |
---|
17 | |
---|
18 | Unlike pragmas that affect the C<$^H> hints variable, the C<use vars> and |
---|
19 | C<use subs> declarations are not BLOCK-scoped. They are thus effective |
---|
20 | for the entire file in which they appear. You may not rescind such |
---|
21 | declarations with C<no vars> or C<no subs>. |
---|
22 | |
---|
23 | See L<perlmodlib/Pragmatic Modules> and L<strict/strict subs>. |
