Thank you James, for the clarifications, corrections, explanations, and link to Pilou.

They help with my better understanding of the node. What it could do, how it could do it.

I'll try and make some corrections, and elaborations, so as to not mislead.

The weaving was an attempt at an example.
If each input array represented (points of) one warp thread...
Output might represent weft thread location, for additional up/down weave information, somehow ???
