One way that has been suggested to deal with double definitions of overloaded methods is to replace overloading with pattern matching: object Bar { def foo(xs: Any*) = xs foreach { case _:String => println("str") case _:Int => println("int") case _ => throw new UglyRuntimeException() } } This approach requires that we surrender static type checking on the arguments to foo. It would be much nicer t

More recently (Oct 2016, six years after the OP), the blog post "Scala and 22" from Richard Dallaway explores that limit: Back in 2014, when Scala 2.11 was released, an important limitation was removed: Case classes with > 22 parameters are now allowed. That said, there still exists a limit on the number of case class fields, please see https://stackoverflow.com/a/55498135/1586965 This may lead yo
I am playing around with lazy functional operations in Java SE 8, and I want to map an index i to a pair / tuple (i, value[i]), then filter based on the second value[i] element, and finally output just the indices. Must I still suffer this: What is the equivalent of the C++ Pair<L,R> in Java? in the bold new era of lambdas and streams? Update: I presented a rather simplified example, which has a n
