[MATRIX-SIG] Change slice object?

Right. And also for indexing with a single number, e.g. a[5].

True. Still it would break code that relies on the current interpretation.
It would probably break my netCDF module, for example.

None at all, because only arrays use multidimensional indexing and
slice objects!

That could easily be done, but what would it be good for?
