Or just program a module in C or Cython.
You can do that in Nim - it compiles to C.
If you have no previous knowledge of C, with Nim you get C-like speed with Python-like easy to write syntax.
I like Python; I just wish I could say the same for its developers...
Including Cython. I mean, if you've got a C library, sure, interface it with Python; but unless you want something to be called from something else in addition to Python, dropping to C for performance needn't be the default choice in Python; that's the whole reason Cython exists.

I find Go’s ergonomics to be worse than Python but better, mostly, than Java.

And, still, including Cython.

This is surprising. I'm a Python developer, and I still prototype new features in Go.
