Original toplevel document

Scala Traits
h each class must inherit from just one superclass, a class can mix in any number of traits. Traits are used to define object types by specifying the signature of the supported methods. Scala also allows traits to be partially implemented but <span>traits may not have constructor parameters. A trait definition looks just like a class definition except that it uses the keyword trait as follows: trait Equal { def isEqual(x: Any): Boolean def isNotEqual(x: Any): Boolean = !
