/* FIXME: This exposes a problem in the representation.  Is it 
   possible to have an exponential and a polynomial together?
   
   The first assignment constructs "a  ->  {2, *, 3}_1",
   while the second adds 5 as a polynomial function.

   The following two representations are not correct:
   "a  ->  {{2, *, 3}_1, +, 5}_1"
   "a  ->  {{2, +, 5}_1, *, 3}_1"
   
   The right solution is:
   "a  ->  {2, *, 3}_1 + {0, +, 5}_1"
   but this exposes yet again the "exp + poly" problem: the representation 
   is not homogen.  Going into a Taylor decomposition could solve this problem.
   
   This is too difficult for the moment, and does not happen often.
