Title: Default joiner to an empty list in join

It 'feels' like join should be able to join a list without having to pass a joiner. I'm not sure if this is something you want, but I figure'd I'd throw it out there. I wasn't sure if it should default to list or binary. Also not sure if I should have added defaults for the other join cases. Are they ever meant to be used anyway?
