Is it possible to modify this code to see where the modules are being called from? For example, to see that List/Util.pm is being called by File/Copy.pm?

    Sure, we can use caller to do that:

    #!/usr/bin/env perl
use strict;
use warnings;

BEGIN {
    unshift @INC, sub { warn "Loading $_[1] from " . (caller)[0] . "\n
+"; 0; };
}

use File::Copy;
