This relates to the Dolphin variant of Smalltalk.
I'm digging around in the image to try and figure this out but haven't find the correct method invocation yet and I'm hoping someone might be able to help shortcut this process. What I'm trying to do is to find all methods (either within the entire system or, preferably, just within a single class) which refer to a given string, symbol, or method. I've found the #references family of methods in SmalltalkSystem but have not had luck figuring out how to get them to give back something resembling what I want.
