Hello :slightly_smiling_face:, 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) }```
