I am having trouble overriding the "print" builtin.
Here is an example that should override both "open" and "print".
#! perl -w

use strict;

use subs qw( open print ) ; 

print 2;
open(1,2) or die "$!:  open() error";


sub open { CORE::print $_[0] + $_[1], "\n" }
sub print { CORE::print $_[0] + 10, "\n" }

Output is

23
instead of
12
3

It looks like "open" is being overridden, but not "print".
