sub definitions within control structures don't really work how you want them to work. Your my_print function only gets defined once; not each time around the loop. If you want to redefine the sub each time around the loop, use an anonymous sub (a.k.a. closure; coderef) - which can be given a name by assigning it to a glob.

This works:

use strict; use warnings; no warnings 'redefine'; # stub to declare sub name, allowing it to be used # as a bareword later on sub my_print (); foreach my $i (0, 1) { *my_print = sub () { print "[$i]\n"; }; my_print; }
package Cow { use Moo; has name => (is => 'lazy', default => sub { 'Mooington' }) } say Cow->new->name
