Do you have an example code snippet of some real code that exercises this exception here or motivation on why this change helps? It's a bit hard for me to think about when there would be two return expressions after one another

[cerdelen]

Not sure if it does have some real life reason to ever have 2 return statements in a row. But just using the example from the issue itself i could see that indeed just putting 2 returns in a row does reduce the level which surely isn't intentional.
