Scala enumeration to int

Question

Is there a way to identify that a given object is an Enumeration value?

x.isInstanceOf[Enumeration.$Value] doesn't seem to work, and from what I understand of path-dependent types, shouldn't.

I'd like to write a function that given any Enumeration value, returns its id. Alternatively, an implicit that converts the Enumeration to Int would also be great.

Answer 1

x.isInstanceOf[Enumeration#Value] works for me. From the specification, Section 3.2.2 "Type Projection".
