StackCell

[DzenanJupic]

I couldn't stop thinking about how to maybe abstract all the unsafe stuff into a single module. This StackCell should be sound (maybe I made a mistake), and could potentially be used.

This is just a sketch though. Maybe I made a mistake, and the code is also not especially clean yet.

It would be good if we could see a working prototype to test, then we can reshape the project around it.

Actually, this solution isn't quite sound yet, since there's a mutable reference to the value on the stack. value has to be wrapped in an UnsafeCell, and we can only hold a shared reference to it. I don't have time for fixing the code or integrating it into the project right now but might get to it on one of the following evenings.
