   5  =head1 NAME
   6  
   7  subs - Perl pragma to predeclare sub names
   8  
   9  =head1 SYNOPSIS
  10  
  11      use subs qw(frob);
  12      frob 3..10;
  13  
  14  =head1 DESCRIPTION
  15  
  16  This will predeclare all the subroutine whose names are 
  17  in the list, allowing you to use them without parentheses
  18  even before they're declared.
  19  
  20  Unlike pragmas that affect the C<$^H> hints variable, the C<use vars> and
  21  C<use subs> declarations are not BLOCK-scoped.  They are thus effective
  22  for the entire file in which they appear.  You may not rescind such
  23  declarations with C<no vars> or C<no subs>.
  24  
  25  See L<perlmodlib/Pragmatic Modules> and L<strict/strict subs>.
