I don't see how it would have any effect at all, unless the P5 ref happened
to be to a typeglob, or had both array and hash semantics tied to it.
The regular $$x, @$x, and %$x look much like they do in P5.

There are a several syntax errors in there, and we currently don't
allow assignment to a capture, only binding. Semantically, I don't
know what such a construct would buy you over the already defined:
my (|x Dog: Str $name, Num :$legs) := \($spot: "Spot", :legs(4));
