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 parentheseseven before they're declared.

Unlike pragmas that affect the $^H hints variable, the use vars anduse subs declarations are not BLOCK-scoped. They are thus effectivefor the entire file in which they appear. You may not rescind suchdeclarations 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.
