looks okay, could do with a test:

scala> {def bar(a: Int)(implicit b: DummyImplicit)(implicit c: DummyImplicit) = 0; bar _} //print

{
  def bar(a: scala.Int)(implicit b: scala.Predef.DummyImplicit)(implicit c: scala.Predef.DummyImplicit) = 0;
  {
    ((a: Int) => bar(a)(Predef.this.DummyImplicit.dummyImplicit)(Predef.this.DummyImplicit.dummyImplicit))
  }
} // : Int => Int

be emitted as abstract.
