What you’re doing here, is assigning the elements of an Array but Lookinside to
a normal Array. The elements of the Array do not have any roles mixed in, so
you wind up with a normal Array with normal elements in them. Perhaps you
meant:
my @y does LookInside = @x;
Here you create an Array @y with the role LookInside mixed in, and *then*
assign the values from @x.
