The compilation callable was broken for the example of the lowercase function (in 2 different ways in the different snippet as the first one was attempted to be fixed in #3771 but my comment asking to remove the return statement inside the compiled expression was misunderstood and the other return statement returning the compiled expression was removed as well.).
