subs(3pm)
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
declarations with "no vars" or "no subs".
- See "Pragmatic Modules" in perlmodlib and "strict subs" in strict.
