I'm afraid the *why* doesn't matter much now. We (or I perhaps) made that
decision eons ago and we stick to that now for compatibility. In hindsight, I
think we should've designed it differently.

The reasons why we went with that decision are basically:

  1. We didn't originally intend to just have one argument for each

  2. We wanted to pass in different types, and ... is still usable for single
     arguments of different types in ways we'd otherwise have to use some funny
     union or typecast tricks to achive.
