Indeed, in addition I had to use intermediate classes (that implement
some `inline const * & get_*(void) const;' methods) to get the following
protected members (in order to use them in a function for Python output
format):

basic::precedence
pseries::seq
pseries::var
pseries::point
relational::o
expairseq::seq
expairseq::overall_coeff
  
Some of them can be determined indirectly (e.g. relational::o -- by
info method, basic::precedence -- look-the-source), some not
(e.g. pseries::var).

It would be great if GiNaC could provide the corresponding getters. If
not, not a problem -- one can use varios work-arounds.
