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.
