subs - Perl pragma to predeclare sub names
- use subs qw(frob);
- frob 3..10;
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 $^H
hints variable, the use vars
and
use subs
declarations are not BLOCK-scoped. They are thus effective
for the entire package in which they appear. You may not rescind such
declarations with no vars
or no subs
.
