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.
