Only that no-one has implemented it, I guess. If you want to then
that'd be cool :-).

To be generally useful for debugging, it would probably be good for
the error message to also mention which dimension is involved, and/or
the actual size of the array in that dimension. You can also get such
error messages from expressions like 'arr[i, j, k]', after all, where
it's even less obvious what went wrong.
