There is another reason to avoid this.
Note that if I have two consecutive blocks of memory:
0...4
and
4...8
If we define an array that points to the first block as a
pointer to 0 and a pointer to 4, then that array also
effectively points at the second block (4...8). The way the GC
works, it will not release the second block as long as you have
a pointer to the first, even though the second pointer is not
technically pointing at the block.

That's a good point. I also shows another danger of ptrEnd: Not
only is it not a reference to the current range, it could *also*
be a reference to an un-related range.
