I don't know much about Scala, but I do know a little about George Orwell and his rules for writing English, so I found this comparison by Peter Hilton both funny and interesting:
There are two things that you might not know about George Orwell’s advice to writers: 1. George Orwell’s real name was ‘Eric Blair’. 2. He was really writing about Scala programming, not English.
You’ll have to trust me (or Wikipedia) about the pseudonym thing. That he was writing about Scala, however, is self-evident once you consider the rules individually.
