When different wires/batches receive an evaluation claim at the same point, it makes sense to precompute the eq table at that point just once and clone/use it where needed. There are some nuances:
- This has a cost in memory allocations
- The cost of computing an eq table is one multiplication pass. If the cached claim is being folded along others, it only saves operations if it constitutes the first claim (folding coefficient $r^0=1$)
