At any rate, I guess this is diverging from the real > discussion of anonymous functions :) If you've ever tried to hack on the source to anything that you didn't write that also uses globals throughout (Gallery2, for example), you know how hard it is to track down a single layer of scope that can be defined [somewhere else]. Tracking this up the chain like a bubbled exception sounds like a nightmare for debugging/comprehension, and IMO it's too magical. One layer of scope might be useful: $_PARENT ? More than that, and my head starts to hurt. S
