I think we could get into trouble here if the expression is supposed to be evaluated at global scope, in which case scope will be NULL and will fall back to the executed scope here. So we'd have to distinguish an explicit scope vs the fallback to the executed scope separately.

Ah, forgot about global being NULL. Seems like the signature should allow providing the explicit vs execution scope? I'm out of my depth though so feel free to change/modify this.

I'm a bit unsure on whether there's a better way to do this though...
