[Pharo-dev] Getting all classes referenced by a method

Hi, it want to rewrite the SmallLint rule which checks whether an abstract class is referenced. First question is whether the rule is really important, because sometimes there are abstract classes with some utility class methods, so maybe we should check whether they are “instantiated” with #new or #basicNew. Now the real question is how do you get all classes referenced by a method. So instead of performing a rule check on a class, do it on a method and find if any of the accessed classes is abstract. Uko
