Shaped Arrays and Native Shaped Arrays already use one contiguous blob
to store all their data; in Shaped Arrays that's an array of pointers to
the stored objects, in a Native Shaped Array it'll be like a big array
of 32bit integers or whatever you have.

and I find myself wanting to implement a role "Shaped" and applying it
to List, for an immutable shaped list, whose implementation packs its
elements for o(1) lookup... on my ever-lengthening to-do list

If it's a shaped multidimensional array, you can call the .shape
method
my @a[3;3;3];
dd @a.shape; # (3,3,3)
If it is not, then your workaround appears the way to do it.
