A few days ago I tried to define !| || and !|! as binary methods in Squeak. Today I tried the same with Pharo. They all fail because the parser interprets the '|' character (the second '|' character in the case of ||) as the beginning of the declaration of local variables. Is this a parsing error or the way Squeak/Pharo is intended to be defined? Now you might think !| and !|! are pretty weird (which doesn't invalidate my question) but I think || is pretty natural as a binary method!
