but it is the same essential property whoever has it, and in particular has
the same kind. A door and a scene could both have the property "style", but
it would have to hold the same kind of value in each case.

property acting as its negation, "closed"; or valued, such as "carrying
capacity". These have different semantics, and very different run-time
implementations. In this section of code, we deal with what they have in
common.
