This argument is true for every function. I don't see why
  if test then a else b
    is necessary, but
  foldr with_function f initial_state i on_list xs

If you really need "then" and "else" we could certainly construct some 
library functions, to let
  if test `then` a `else` b
    work, or
  if (test expression) then (a expression) else (b expression)

 infixr 0 then, else

data Else a = Else a a

else = Else

 and so on ...
