Err, technically, aren't functions and constructors mutually exclusive? So if something is a function, it's, by definition, not a constructor?

I guess what Eugene Kirpichov meant was that not being a function (and being a constructor) isn't sufficient, it must also be a constructor of the correct type, e.g. f Nothing = ... f (x:xs) = ... isn't correct, however it pattern matches on constructors only. -- Felipe.
