in reply to overwrite builtin functions ( system, chdir )

Would something like this do? 
use subs 'system','chdir','glob';

glob; chdir; system;

sub system {print "system\n"}
sub chdir { print "chdir\n" }
sub glob { print "glob\n" }

__OUTPUT__ 

glob
chdir
system

    Hi,
    No, that is not enough, I like to overwrite the functions global regardless of the namespace.
    So that this work: 
    *CORE::GLOBAL::system = sub { print "system\n" };
*CORE::GLOBAL::chdir = sub { print "chdir\n" };
*CORE::GLOBAL::glob = sub { print "glob\n" };
package xyz;
glob; chdir; system
