I think actually Odin, although I was surprised by that (being more of a Zig fan). Odin has some neat convenience features which are nice for higher level code, while Zig can be a lot more 'draconian' by enforcing correctness even at the cost of some "line noise" (but I guess both languages are still in flux, so that might change).

As for Nim I enjoyed it initially (because of the Python vibes I guess) but the automatic memory management gets confusing quickly. IIRC there's quite a few different reference types - but maybe that has been simplified in 2.0

PS: Even though the bindings are auto-generated, I still try to make them 'language-idiomatic' by injecting some 'semi-manual' mappings for things like naming conventions or implicit type conversions, ideally getting the API close to what a 'native' API would look like - at least that's the goal.
