Should we expect `function-expression-body`  to have detected the following:
```fun foo(): Any {
    return bar { return@bar null }
}```
as it could be written as
```fun foo(): Any = bar { return@bar null }```
?

It seems to be caused by the existence of the `return` keyword twice in the body of the function. The rule does not apply when it founds that keyword more than once in the body.
```        block
            .takeIf { it.containingOnly(RETURN) }
            ?.takeUnless { it.countReturnKeywords() &gt; 1 }```
I cannot recall why I added that last line. When I remove it, no unit tests breaks... Please create an issue for it and I will have a look at a later time.
