Potential syntax:

class TheObject {
    operator fun ++() { ... } // Unary operators
    operator fun +(other) { ... } // Binary/logical operators
}

Both functions would require a return value, would also be nice to integrate this with type declarations, so it is possible to limit the accepted other parameter types (and reject at evaluation if an argument is invalid, either during resolving (if possible) or at interpretation).
