1. Implicit parameters

val a: A = ...
implicit def (a: A): B = ...
val b: B = a

2.

T % String
  for T is sub-type or implicit-converted to String


3. Parameter groups

fun1(...)(...)(...)
  function can have multiple parameter groups

the last-one can be made implicit

they can depend on the abstract parameters of prev-groups:

  def mungeData[D](d: D)(implicit m: Munger[D])

and this works for higher-kinds:

  def mungeData[M[_], D)(d: D)(implicit m: Munger[D], each: Each[M])

4. Companion objects - with the same name as a trait.

any "implicit val <name> = new <trait-name> ..." will be available anywhere a <trait-name> is needed withou imports.

5. Implicit Classes

implicit class Person(name: String)

implicit class Person(name: String)
implicit final def Person(name: String): Person = new Person(name)
