I know (from experience) and understand why goto's and globals are 
(usually) evil, I know why public attributes can be harmful - in 
languages that don't support computed attributes, that is -, well, I can 
understand and explain most of the usual and some less known "golden 
rules" (law of demeter etc), and even a couple very local or 
yet-unwritten ones (monkeypatch anyone ?), but I definitively fail to 
see what's your problem with nested classes.
