+  bool operator>(const ElementCount& RHS) const {
+    return Min > RHS.Min && Scalable == RHS.Scalable;
+  }

> Thanks for the review. Strict weak ordering is implemented -- (A < B) and (A >=B) can both be false as long as (A > B) is true.  Is there a case where scalable and unscalable widths would be compared? If so then I can remove the LHS and RHS scalable comparisons from the operator overloads.
I think I'd prefer to just write out the operation in the users for now, until we have some practical experience with what patterns we end up using in practice.
