So there's method CompiledMethod>>senders, but the problem is that it just looks for the message symbol and not class. so for example: ~~~~~~~~~~~~~~~~~~~~~ (WriteStream>>on:) senders ~~~~~~~~~~~~~~~~~~~~~ will also include Object>>asBrick Object>>asBrick ^ GLMMorphBrick on: self asMorph because it sends #on: even though it's on completely different object. Now I understand that this is a dynamic system, so I will never have all senders, but this should be resolvable even through static analysis? So now my question is: Is there an easy way to retrieve the object to which the selector is sent? I can use "CompiledMethod>>messages", but that just returns "a Set(#asMorph #on:)" which is useless here. So do I need to traverse the AST and find it there? Thanks, Peter
