I think the main issue is that Erlang doesn't use currying (IIRC).
Currying makes it MUCH harder to implement varargs functions.  (We
thought this was a good tradeoff - partial applications give Haskell
much more power than varargs would have.)

(Unfortunately I don't know of any good languages with powerful type
systems and vararg functions that can take advantage of powerful
types...  I'd love to give example code here :))
