Missing type guard argument on fromFalsy #252

fromFalsy have this signature:

fromFalsy<V>(val: V|null|undefined): Maybe<V>;

This means that the following produces V=false|string, where it should be V=string:

fromFalsy(false | "some string")

I think the signature should be changed to:

fromFalsy<V>(val: V|null|undefined|false): Maybe<V>;
