Just a bit curious, what is the lambda fun intended to do? fun(a) -> "a" end looks to me as it would only evaluate if called with a single symbol a as arg and (silently) fail otherwise. If I extend a littl I get: 10> [(fun F(a) -> "a"; F(_) -> nothing end)(R) || R <- [a, b, c]]. ["a",nothing,nothing] Don't mind if the question is stupid, I'm still learning...
