I'm not sure how should support slicing. The most economic way to implement
this range is to use a static array and an index indicated the next value.
Slicing this range would require either:
 - to store an extra index in the range... that would be sad IMHO, because it
is often not needed.
 - to return something else than a "range":
   - a struct containing the static array and the slice. That seems to be
overkill.
   - a dynamic array. Then the slice would not be a value type like the range
is.

The dynamic array option is the most reasonable to me.
