Comment #7 on issue 3224 by stephane.ducasse: Migrating MethodReference to MethodReferenceWithSource
http://code.google.com/p/pharo/issues/detail?id=3224
The problem is that MethodReference was also used to just be an object that represent a class name and a selector. In addition it was also used to wrap a compiledMethod and as such a compiledMethod got a sourcePointer (I image).
