I see the problem.
The first possible solution that comes to my mind seeing this is to
make array1[0..0] and array1[$..$] equal.
array1[$..$] could point to the begin of the array.
Since the slice length is null, it shouldn't matter - would it?

Second thought, why not ignore empty slices at all by telling
the GC that the pointers doesn't hold any data.

Anyway, I guess there some things I missed. ;-)

Yes, it does. :)
