Array indexing and slicing

Actually I don't think that can be true. That would only be the case if the
indexes were defined at compilation time. Assuming positive indexes only, the
following code...

int index = get_int_from_user();
value = array[index];

could be translated into:

value = *(&array_contents + (index * element size));

If we allow negative indexes then that doesn't work. "index" is computed at
runtime so the code generated must change to allow that. At least that's the way
I see it.

About bounds checking, I didn't mean to imply it depends on the syntax.
