Function should have 'operator' modifier

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 }
