I meant it also for the (unwittingly) left-out part of your comment. Firstly, by saying this parrot will explain "everything that you need to know ..." you're pushing your own standards onto everyone else. Maybe the OP really wants to understand it deeply and learn about edge cases, and understand how it really works. I dont think I would rely on a statistical parrot (yes, that's really how they work, only on a large scale) to teach me stuff like that. At best, they are to be used with railguards as some kind of a personal version of "rain man", with the exception that the "rain man" was not hallucinating when counting cards :)
