NAME
       subs - Perl pragma to predeclare subroutine names

SYNOPSIS
           use subs qw(frob);
           frob 3..10;

DESCRIPTION
       This will predeclare all the subroutines whose names are in the list,
       allowing you to use them without parentheses (as list operators) even
       before they're declared.

       Unlike pragmas that affect the $^H hints variable, the "use vars" and
       "use subs" declarations are not lexically scoped to the block they
       appear in: they affect the entire package in which they appear.  It is
       not possible to rescind these declarations with "no vars" or "no subs".

       See "Pragmatic Modules" in perlmodlib and "strict subs" in strict.
