Inheritance can be a problem, but I was thinking more of the architecture, what calls what, who is in control, where are the various tasks done, what are the interactions... I'm not sure how a simpler type system would help with that e.g finding out which module does the task of interest, but I don't know Go. [ Design patterns were supposed to help with this, with recognizable groups of classes. Sounds like a good idea, but I haven't found that, but maybe I don't know them well enough, or projects don't them well enough. ]
