A function marked @creates(PhysShape) makes a handle one marked @releases(PhysShape) gives back.
ludic deps --resources lists every creating call whose handle is thrown away, or bound to a local
that is never released, passed on, stored or returned, and resource_drops is a number --check
ratchets. A test: a thrown-away create and one bound and never handed on are the two found; one
stored in a state and one released are not. A record's owned fields and a borrow form (a shape
used by several scaled ones) are the second half, with a resource type.
