=head1 SYNOPSIS |
| 10 |
|
|
|
| 11 |
|
|
use subs qw(frob); |
| 12 |
|
|
frob 3..10; |

|
=head1 DESCRIPTION |
| 15 |
|
|
|
| 16 |
|
|
This will predeclare all the subroutine whose names are |
| 17 |
|
|
in the list, allowing you to use them without parentheses |
| 18 |
|
|
even before they're declared. |
| 19 |
|
|
|
| 20 |
|
|
Unlike pragmas that affect the C<$^H> hints variable, the C<use vars> and |
| 21 |
|
|
C<use subs> declarations are not BLOCK-scoped. They are thus effective |
| 22 |
|
|
for the entire file in which they appear. You may not rescind such |
| 23 |
|
|
declarations with C<no vars> or C<no subs>. |
| 24 |
|
|
|
| 25 |
|
|
See L<perlmodlib/Pragmatic Modules> and L<strict/strict subs>. |
