It been a while since i played with Rails so was surprised to hear that Rails is now multithreaded. Has any one here deployed Rails in this configuration and is it stable?
I dont believe Duck typing and type inference are really the same thing.For duck typing the type is unimportant, it only cares about the operation, types matter for type inference. The behavior of structural typing in languages such as Scala are is closer to Duck typing IMHO.
