Sigils indicate overall interface, not the exact type of the bound +object. Different sigils imply different minimal abilities.
I see no mention of C<@@x> in this section. I would assume that C<@@x> may be bound to any object that does the C<Multidimensional> role, with a note to the effect that the C<Multidimensional> role does the C<Positional> role (and thus anything that C<@x> may be bound to, C<@@x> may also be bound to). -- Jonathan "Dataweaver" Lang
