  trait IntToLong:
    def apply(v: Int) : Long

  inline def convert1(       f: IntToLong) = ???
  inline def convert2(inline f: IntToLong) = ???

  convert1(_ * 10)  // Compiles Fine
  convert2(_ * 10)  // Error:  Found: Int => Long, Required: IntToLong @InlineParam

Is this supposed to work at all?

The workaround does not help (same result). The problem is probably deeper
