[Pharo-dev] List methods with problematic source

Hi guys, How can I collect a list of methods with undefined classes in its source? Example: I’ve recently saw that Comanche http server had a package that won’t load in Pharo 3 because is using FileDirectory. Comanche now loads alright after a patch but.. Instead of iterating lazily this kind of problem in other packages, I would like to make a script that lists all this kind of cases in a given package. BTW a script like this would help to anticipate potential problems to other developers porting a product to Pharo When inspecting one of this methods I’ve sent #recompile to see if it raises an exception but it isn’t. How can I perceive, using code, that a compiled method has this kind of problem? sebastian o/
