Erg looks fun for small programs. Though Erg's syntax choices seem less Pythonic than I'd expected. Interesting though, some of the idioms seem handy.

Though Nim definitely can be described as a statically typed Python-compatible language! I haven't used them but https://github.com/Pebaz/nimporter https://github.com/yglukhov/nimpy both seem great. Nimporter in particular looks fantastic for writing fast python libraries.

Actually come to think of it that might be the easiest way to write fast KiCad 6 plugins.. I really want to try making a native KiCad autorouter. But I don't want to figure out the C++ plugin setup and since KiCad 6 the Python APIs seem better documented and supported anyways. Problem is that Python would likely be too slow. Nimporter could be perfect. It looks really simple to setup.
