--- Comment #3 from Manu <turkeyman at gmail.com> ---
I've just run into this issue.
I was trying to fix `destroy()` not working on C++ classes, and quickly
realised I needed a reliable way to detect C++ classes!

So, we can't fix destroy() until we have this, or an alternative accepted
solution...
