Would they be recognised as scalars by Python? In particular, could you
use one as an index? Personally, this is what has bit me in the past: I
could use A[3,2] as an index if A was type "Int" but not if it was
"Int16" for example.

In any case, the type of A[3,2] should NOT depend on the precision of
the numbers stored in A.

Frankly, I have no idea what the implimentation details would be, but
could we get rid of rank-0 arrays altogether? I have always simply found
them strange and confusing... What are they really neccesary for
(besides holding scalar values of different precision that standard
Pyton scalars)?
