ReadonlydisposedCheck if this handle has been disposed
ReadonlywrappedThe raw kernel shape handle
Manually dispose the kernel handle
Alias for Symbol.dispose — required for Deletable compatibility.
Register a callback to run when this handle is disposed, before its kernel slot is released. Used to release dependent resources tied to this shape's lifetime (e.g. its cached sub-shape handles). Callbacks are invoked once, in registration order; a callback that throws is swallowed. Registering on an already-disposed handle runs the callback immediately.
A shape wrapper with Symbol.dispose for auto-cleanup.
