| I think that's only possible when you know the array's dimensions at
I guess I was unclear. Each array knows its own shape, it's part of
its "dynamic" type. Size is one invariant. If they don't match
then that indicates the arrays aren't of the same type.
If you do want to assign an array to another you need to make
sure (explicitly) that their dynamic types agree -- that is, make sure
they are of the size.
