I have closures in several places in the object graph. These are objects
with some pluggable functionality, which I rely on.

OK. The question is then if those closures are "clean" or not. In other words, what's their scope? 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...

I know you already have your application written, but I am trying to explain how I was able to use Fuel for this case...��

��

Just for my better understanding, I like to ask: The FLMethodChanged
errors will show up for *EVERY* method of a materialized object (Since
the bytecodesHash changed for every method) or just those methods which
involve fuel-persisted MethodContexts? (Sorry, if the question is
stupid, but I am rather new to Fuel internals)

As far as I can remember, the latter.��

Cheers,

Andreas
