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…

I’ve always liked how IntelliJ (and friends) add extra context inline with the code, like inferrred types, and parameter names when calling functions.
That might be more accessible than relying on colours…
