Concurrency introduced us to the “what color is your function” problem, and I suddenly find myself imagining…

What if Xcode *actually colored* the code based on its isolation? All MainActor code is black, all ambiguous code is gray, all actor-bound code is a color picked for that actor…

@davedelong I have heard variations of this a lot! And while I do find the idea fascinating, one thing I never struggle with is actor ambiguity. I think it’s really similar to (but definitely not identical to!) having an intuition for the `self` variable. But having hover or some other kind of at-a-glance info for the current function scope could be handy for sure!
