Do they refer to variables defined outside the closure (in which case you would need the methods contexts / stack) or are they clean in the sense that you could be able to replace them via a string and then compile them again ? Some time ago we added a #isClean to BlockClosure. You can test a few of your closures to see if this is the case or not. Btw, I have an application for a client in which we also have closures to define some pluggable behavior. But what I do is: 1) guarantee they are 100% clean (does not go outside of scope) 2) aside from the "block" instVar I also add another instVar which is the "string" version of it. Then I always implement #fuelIgnoredInstanceVariableNames to ignore all those "block" instVars, yet DO NOT ignore the "string" like of those closures. Then, of course, the getter of the block instvar does a lazy compilation if the block instVar is nil...
