Following a discussion with a friend about operator overloading. I am looking at creative and/or useful example usage of operator overloading in Scala. I have some cool illustrations:

  • Mathematical constructs, like linear algebra or complex numbers (+ * -)
  • Mimicking shell pipe and redirections (| > < >>)
  • Alternative expressions in Grammars (|)

Have you other nice examples ?

    The ones I don’t mind using occasionally:

    • A general-purpose pipe |> (e.g., someValue |> println)
    • := one some structures like observable value holders to mimic assignment
    • Databinding in UI programming with <=> (two-way), <== (one-way) (e.g., field.enabled <=> options.isEditable
