This contribution uses a loopline for gathering the values.
The stub generator is incorrect for some languages, at least Clojure and Ocaml, because they read the input line by line instead of splitting the unique line.
There was a similar bug in Perl. This contribution also fail for Clojure and Ocaml.
In this case, this can probably be fixed by using a loop instead of a loopline, but as I have shown, there is already contributions using this loop style.
