Using unicode symbol as an infix operator in Scala

Does anyone know why the following code doesn't recognize ∙ as a valid infix operator?

object Main extends App {
  val c = (I() ∙ I())
}

sealed abstract class Term 
case class I() extends Term
case class ∙(x: Term, y: Term) extends Term
Solution

  • Define ∙ as method on I.

    sealed abstract class Term 
case class II(x: Term, y: Term) extends Term
case class I() extends Term {
    def ∙(o: Term) = II(this, o)
}

    Now I() ∙ I() will work, returning II.

    Not sure what you are trying to achieve, though.
