class :=[T, Q] extends AnyRef

Allows to provide default value for type parameter. NOTE: Be careful when you use this. Result type inference order reasoning can be very tricky.

scala> def foo[T](implicit default: T := Int, ct: ClassTag[T]) = ct.toString scala> foo Int scala> foo[String] String

For foo: useDefault[Int] wins over useProvided[Nothing,Int] For foo[String]: useProvided[String,Int] applies, useDefault does not
