Core without membership tests means that the useful intersection of Core and PRD is close to nil, whereas the useful intersection of BLD and PRD is not, which would make Core a strange animal...

(That's assuming that the membership relations in PRD and BLD are the same. If it appeared that they are different, a different syntax will have to be introduced for one of them, as Chris pointed out; but that is a different discussion).
