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 package 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.
