|

|

11 | use subs qw(frob);

14 | =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>.
|
---|

|
---|
25 | See L<perlmodlib/Pragmatic Modules> and L<strict/strict subs>.
