Dear All, What is easy to do is to add to function class a primitive feature analogously to their knowledge of derivatives. Then, integral::eval_integ() may call such methods to evaluate simple integrals of plain functions. If this looks reasonable to be included in GiNaC, then I may write such a patch.
