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 the section on Pragmatic Modules in the perlmod manpage and the section on strict subs in the strict manpage.
