I merely explained why it didn't work, for any passerby. I don't think the rules are hard to understand once described. There's basically only one of consequence—if writing outside the current scope there neeeds to be a clarifying statement first to avoid ambiguity. Unfortunately that prevents usage in a lambda. However, I don't think complex functionality belongs in them either, so not a big loss. See the Beyonce rule mentioned elsewhere in this thread.
