Ah, okay, that fully answers my question, thanks. That makes it impossible 
though to apply the same technique to a single variable twice, without 
further tweaks (either versioning of the variables, or actually stacking 
the shadowing itself).

Honestly though, I don't think that's going to be a big issue in practice.

I think you didn't misunderstand it. But it might be beneficial to have a 
few additional explanatory words in the documentation nevertheless :)

Thanks,
