Yeah, but Go is also worse (in my experience) than most, if not all, of the other general-purpose languages I've used, for this niche.

For instance, Rust is actually pretty great in this space, despite being very ... not-python, and Java also has decent libraries. Then C++ (and Fortran!) are good for a very different reason than python, "on the metal" performance, which Go also isn't a great fit for.
