MACLISP was one of the first LISPs around (way before Emacs, way before
you or me saw a computer). Serve yourself:

  http://www.maclisp.info/

Specifically here:

  http://www.maclisp.info/pitmanual/number.html

More specifically:

  http://www.maclisp.info/pitmanual/number.html#9.18

Those people did it this way... back in the 1970s because that's
the was mathematicians brains work. If they get to design an
n-ary addition or multiplication operator, /this/ is the way
they'd do it.

Emacs Lisp just inherited that. It was in LISP's "way of thinking"
right from the beginning.

Just because you don't like it it's not going to change.
