Unable to create a routes file with same name as a method in Predef

I created a Play routes file with

/some-endpoint                         identity.Routes

The compiler barfed with this:

stable identifier required, but scala.Predef.identity[Nothing] found.
[error] ->          /some-endpoint                          identity.Routes

Looks like the compiler can't differentiate between a user-defined name for a route file and the Predef identity method. Is this a bug in Play.
