The title is misleading and wrong. The article is about a new library that lets you write kernels in C++.

There is however a kernel for C++ that you can try here: https://mybinder.org/v2/gh/QuantStack/xeus-cling/stable?file... if interpreted C++ is your thing :)

Read the whole article. It starts by introducing xeus and xeus-cling for those who don't already know about it, then gets to the subject of the title, xeus-python, which is based on xeus and, indeed, written in C++:

Having a C++-based Python kernel available doesn't mean "Jupyter switches to"

Playing with that xeus-cling notebook, does anyone know how to curb the `error: redefinition of` errors when changing code and rerunning it?

This bug is prohibitive enough I suspect it will be a deal breaker for the majority who want to use this kind of tech.
