Good summary, I haven't touched threads but I'd agree with everything else. I'd also add that since the language feels dynamic, I feel like my code is less structured, but I think this might just be because all the boilerplate you have to write in other languages isn't there. So maybe my code is just as unstructured and with nim I can't be fooled by boilerplate into thinking it is.

I've been following the nature of code and making a little 2d platformer at the same time using nim + raylib. Compiling to wasm I found to be even simpler than when doing the same thing with C++. It's really nice being able to compile to native or wasm with a single compiler flag.
