Assuming we're talking about D slices, Yes. (It could be a
user-defined type with surprisingly different semantics.)

That changes element values.
Ok. But which element(s)? In my specific case, I was using [].
Is
waste[] = waste[0..$-1];
even semantically meaningful? Because the LDC compiler had no
problem compiling it.

That makes slice refer to a different set of elements. In that
example, the slice does not include the last element anymore.
