C++ implementation of the Jupyter kernel protocol

See the post on the Jupyter blog for more context which has a section on xeus : <a href="https:&#x2F;&#x2F;blog.jupyter.org&#x2F;interactive-workflows-for-c-with-jupyter-fe9b54227d92" rel="nofollow">https:&#x2F;&#x2F;blog.jupyter.org&#x2F;interactive-workflows-for-c-with-ju...</a>

Interesting. Are there any examples of this library being used so far? Can anybody familiar with the topic elaborate on how much can it actually simplify things and what&#x27;s left to figure out?

I wonder what was the reason this was written in C++, not in Python or other interpreted languages? Is speed a concern here?
