in thread Implicit assignment to $_

You probably ran Perl with -w then, because it's warnings that produces that error.

package Cow { use Moo; has name => (is => 'lazy', default => sub { 'Mooington' }) } say Cow->new->name

    Confirmed (with 5.14.2):

    $ cat test.pl
use strict;
"Test A"or"Test B";
print;
$ perl test.pl
$ perl -w test.pl
Use of uninitialized value $_ in print at test.pl line 3.
