How often did you get a smartass/extremely literal answer? The example function question has some ambiguity someone who just didn't care could exploit:
Request: "Write a {{language}} function things() that returns a list with three values: the number 5, the string 'foobar', the capital city of Spain.
[5.0, "fubar", "the capital city of Spain"]
would be a way-too-literal answer, or maybe a test input from an exceptional tester.
