Best practices: MUST NOT use "return"

scala

trait Quizful[T] { def fetchList: List[T] } // consumer side someQuizful.fetchList If the List returned above is mutable, what does that say about the Quizful interface?

scala

MUST NOT use "var" inside a case class

scala

Declaring abstract "var" members

scala

What is the returned type of this function: def sayHelloRunnable(name: String) = new Runnable { def sayIt() = println(s"Hello, $name") def run() = sayIt() }

scala

Public functions should have an explicit return type
