Sorry typo. That should be optional.

I never looked into TREX but perhaps I will.

You misunderstood me.
It should be.
array (range 1 to 10) [(1,1), (1,2) ....]
array (range 1 to 10 skip 2) [(1,1), (3,2) ...]
array (range 1 to 100 factor 2] [(1,1), (2,2), (4,3), (8,4) ...]
Perhapes range is not a good word to use. Maybe indices instead.
