 subs - Perl pragma to predeclare subroutine names

SSYYNNOOPPSSIISS #

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

 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.
