Hello 🙂, Is there a style guide or convention for how to declare an infix function?
I wonder what is the officially recommended method, or what is the most used method?

1.

infix fun Class.test(something: Something): Class = this.test(something)

2.

infix fun Class.test(something: Something): Class = test(something)

3.

infix fun Class. test(something: Something): Class { return this. test(something) }

4.

infix fun Class.test(something: Something): Class { return test(something) }
