subs(3)
NAME
subs - Perl pragma to predeclare sub names
SYNOPSIS
use subs qw(frob); frob 3..10;
DESCRIPTION
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 file
in which they appear. You may not rescind such declara
tions with "no vars" or "no subs".
- See "Pragmatic Modules" in perlmodlib and "strict subs" in
strict.
