So one option would be to backport the patch to the Python version you

On a number of your points I agree (see below). However, I think
there is one significant problem with your point of view. In my
roughly 30 years of experience as a chemist and professor using

2) writing

Well, you've missed so much that you clearly just enjoyed writing a

I use Sage for a number of research purposes for which it is the only
system that integrates all the things I need (for example, gfan).

This is such an amusing thread. Try re-reading the thread as if everyone
were arguing that we should improve Maxima because it is open source
and many people can improve upon it. Sure, you'd have to learn lisp
but Guido argues that python is lisp, so is the learning curve so steep?
