Research direction

Start with Cslib/Foundations/Relation/Euclidean.lean at lines 18–24 and read the cited discussion in Simple Laws about Nonprominent Properties of Binary Relations. Determine the intended attribute behavior and scope there; done means the attribute can dualize the relevant theorems to the converse relation.
