.isa() tests
These tests are specific to the .isa() which is attached to the
Perl6 Array "class". Which is actually @array.HOW.isa(), which
is actually just the normal OO .isa(). This test does not attempt
to test anything other than the "normal" behavior of @array.isa()
Further clarification of .isa() can be found here:
