Thanks a lot for your patch, I am currently investigating it. This won't be finished today, hopefully tomorrow. Just one question: You know that this issue has been discussed already with no final consensus? The last rant is archived at <http://www.ginac.de/lists/ginac-devel/msg00259.html>. (I don't see clear yet. This email is just to make sure we don't miss any opportunity.)
At the time I overlooked this message and then forgot, though it seemed relevant. However, my patch will not certainly solve your problem. In Python one can define functions on fly --- that is what you are trying to establish in C++, if I understand this correctly. My patch just helps connecting Python and GiNaC in such a way that the problem is transformed to the Python side where it is not an acctual problem anymore. Thanks, Pearu
