In the reference manual for 1.3.5 ("Generated on Thu Aug 17 15:03:26
2006 for GiNaC by Doxygen") under "GiNaC Namespace Documentation":

• static void get_symbol_stats (const ex &a, const ex &b, sym_desc_vec &v)
      Collect statistical information about symbols in polynomials.

Ok, thanks.

I'm about to write some code to convert a multivariate polynomial to a
recursive form of Horners rule, with "respect to" one symbol at each
level of recursion. I figure f.ex. get_symbol_stats is useful for
