--- Comment #4 from Sam Weinig <sam at webkit.org> ---
Yeah, I'm just going to implement the defineOwnProperty hook. One issue though is that as specified, I need to modify the PropertyDescriptor (see step 3 of https://heycam.github.io/webidl/#legacy-platform-object-defineownproperty) but the hook passes it as a const reference. Seems relatively straightforward to change this in JSC, but I am not clear if that was done for a reason.
