It's probably just wishful thinking, but it would be nice if we used the
same arities here, though...  I don't want to be all imperialist and say
"hey chickeners!  you must change your thing!", but the single-arity
transformers might even be better for yall as well (for source
information, for example; though is that a red herring?).

Consider it! :)
