We discussed about this during the summit. You told me that the issue
was a piece of code that needed optimization, to which I replied that
probably, a C++ .so extension in a Python module is probably what you
are looking for (with the advice of not using CFFI which is sometimes
breaking things in distros).

Did you think about this other possibility, and did you discuss it with
your team?

At the Linux distribution level, the main issue that there is with Go,
is that it (still) doesn't support the concept of shared library. We see
this as a bug, rather than a feature. As a consequence, when a library
upgrades, the release team has to trigger rebuilds for each and every
reverse dependencies. As the number of Go stuff increases over time, it
becomes less and less manageable this way (and it may potentially be a
security patching disaster in Stable). I've heard that upstream for
Golang was working on implementing shared libs, but I have no idea what
the status is. Does anyone know?
