The RFC says this syntax is ambiguous without the parentheses, since
the \ may also be part of a fully qualified type name. [1]
I'm not sure whether it would work if the single parameter isn't typed.
I like the Haskell syntax as well, but I'd also be okay with the fn
keyword if that's what others prefer.
