subs
NAME
subs - Perl pragma to predeclare subroutine names
SYNOPSIS
- use subs qw(frob);
- frob 3..10;
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 $^H
hints variable, the use vars
and
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 no vars
or no subs
.
See Pragmatic Modules in perlmodlib and strict subs in strict.
