10 years ago I've tried to clarify the building metaphor a bit, but it's just one of several used (including the bubbles and the nested russian dolls). It's actually an important metaphor contrast used in the next title, discussing this and [[Prototype]].
The link to the image isn’t working. Also, I don’t know if the “building” metaphor works for me. It implies that global scope is built “on top of” the nested scopes, which doesn’t quite fit, because that implies you couldn’t remove the nested scopes without affecting the global. I think a metaphor like a matryoshka doll may work better.
