/* 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.
