hmm that's cute, you can mis-spell 'is' and the code still works: 
package M1;


use Mouse;

has 'x' => (is => 'rw');
has 'y' => (ks => 'rw');

1;

use M1;

my $m = M1->new(x => 55);

warn $m->x;

$m->x(888);

warn $m->x;

UPDATE it's not that it works because the accessor is not actually formed. It's just no error is thrown. Just put a call to $m->y and you will see Can't locate object method "y" via package...
