This last point is important: we do not want an object's typeof-type to change by giving it a @call property. But we do want to enable call and construct protocols to be built by users, by giving objects @call and @construct properties.

I did not include an Object.isCallable(v) API that returns true if (@call in v), but we could add that. Testing (@call in v) seems simple enough.
