I take this back, the subscripts aren't redundant. We could allow
(here 'a' and 'b' are non-lists):

  f : %f[2,1](a,b,x) --> noun form,
  subst([a = [1,1], b = [1]], f)  --> 1/(1-x),
  subst(a = [1,2,3], f) --> error!

Such a scheme (plus, I suppose, a simplifying push function) would allow
us to do fun things with derivatives of the hypergeometric functions...
