[Pharo-dev] (Ring?) Working with 'virtual' code entites

Hi everyone! As you may know I’m working on code quality/smells/critics. And I want to analyze bigger projects like Moose for example. But Moose works on Pharo3 while my system works on Pharo4. Is is possible to somehow obtain Classes and methods from the repository and perform some analysis on them without installing them in the system? Because in my general workflow I just create a collection of classes like: `packages flatCollect: #definedClasses` and then work with them. So any suggestions are welcome :) Cheers. Uko
