LÃder, you can do something like: class := myCompiledMethod methodClass. class instVarNames select: [ :varName | idx := class instVarIndexFor: varName. myCompiledMethod readsField: idx or: [ myCompiledMethod writesField: idx ] ] because #readsField: and #writesField: are index based. You can also see as an example: Behavior>>#whichSelectorsAccess: that is var named based, but over all class selectors. Guille On Sun, May 6, 2012 at 10:38 AM, Carla F.

Hi! I'm playing with some metaprogramming, and I'm stuck at trying to find out *which* instance variables are referred inside a method. I've found that a CompiledMethod understands hasInstVarRefs, but I don't recognize a method that could tell just me what I'm looking for.
Any leads?
Thanks! Carla.
