That is, if a struct's generic requirements can't be deserialized, drop the struct. This is the same logic that's already in play for enums and (as of the previous commit) classes, so it should be pretty well tested by now. (Hence the sole test I'm adding here, snuck into superclass.swift because it's a superclass /constraint/ being tested.) I don't know of any outstanding issues caused by this, but it was weird to have it for enums and classes but not structs, so here we are.
