Maybe I'll give it another try. I might have gone too deep into the docs, but Nim seemed to get very complicated with all the {.annotation.} to remember
If you're just starting with the language, my recommendation would be to ignore the pragmas. None of them are necessary for basic functionality, and a lot of them are only useful for very specific optimizations. The most useful pragmas in my experience are the pragmas for FFI, async, and memory/side effect tracking.
