Class Any
is the root of the Scala class hierarchy. Every class in a Scala
execution environment inherits directly or indirectly from this class.
Starting with Scala 2.10 it is possible to directly extend Any

, only has
def

The main use case for universal traits is to allow basic inheritance of methods for value classes. For example,
See the Value Classes and Universal Traits for more details on the interplay of universal traits and value classes.
