Re:Kotlin: The Problem with null

Wouldn't this let me call `fn true false` or `fn "hi" 2`? Or the second declaration takes the inferred type of the arguments from the first one?

This isn't two functions: it's actually one function defined by cases. You can think of it as equivalent to
fn x y = case (x, y) of
(Just q, Just z) -> q + z
(_, _) -> 0
but the case becomes implicit in the repetition of the function name at the top level of indentation.
