The block that gets passed into each was designed to take one argument. Each is a block (a.k.a closure, a.k.a lambda function, a.k.a anonymous function) that has a design similar to any regular method or function, for example: def each(arg) do # method body end If you were to pass two arguments to that method you'd have a similar result: self.each(a, b) => Results in something just as nasty. -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
