I would say likewise using static indexing, is it really that slow?

Otherwise, iterate over Pair-like partitions would also be a solution and compare if first.tableDef is second.tableDef, don't know if D has something for this statically available.

Further, I would like to refactor the static if out to an in-requirement, though I'm unsure if in-assertions support arbitrary exception types.
