scala - Ambiguous Class level and inherited method level ClassTag -

i have trait requires function classtag

trait foo[t] {     def bar(a: list[t])(implicit ev: classtag[t]): unit } 

now have class needs extend trait, has uses classtag other methods, e.g.

class myclass[t](implicit classtag: classtag[t]) extends foo[t] {     override def bar(a: list[t])(implicit ev: classtag[t]): unit = { /* stuff */ }     def other(p: map[string, t]) = /* other stuff need classtag */ } 

when compiled error message along lines of:

error:scalac: ambiguous implicit values: both value classtag in class myclass of type scala.reflect.classtag[t] , value ev of type scala.reflect.classtag[t] match expected type scala.reflect.classtag[t] 

is there way can accommodate both class level classtag , override method parent trait?

you can give same name both of them.
