Reports a function that matches one of the operator conventions but lacks the operator keyword.

By adding the operator modifier, you might allow function consumers to write idiomatic Kotlin code.

Example:


  class Complex(val real: Double, val imaginary: Double) {
      fun plus(other: Complex) =
          Complex(real + other.real, imaginary + other.imaginary)
  }

  fun usage(a: Complex, b: Complex) {
      a.plus(b)
  }

The quick-fix adds the operator modifier keyword:


  class Complex(val real: Double, val imaginary: Double) {
      operator fun plus(other: Complex) =
          Complex(real + other.real, imaginary + other.imaginary)
  }

  fun usage(a: Complex, b: Complex) {
      a + b
  }
