That's interesting, since the first thing I did with Ginac over the last 10 days was completely replace all use by Ginac of cln by use of PyObject*'s, which are more like giac::gen, I guess. Incidentally, I invested a significant amount of time systematically learning C++ when I was an undergrad computer science major, so you're right that this likely affects my perspective.
