That hasn’t been my experience with Nim so far. Both Claude 4 and GPT5 both one shot Nim code almost perfectly now. They even made a Nim JavaScript app for me.
On top of that I’ve been able to “vibe” code a couple of different libraries for Nim. The bigger limits with LLMs is still “deeper” and loosing track of what it’s doing.
It helps that Nim doesn’t have much unique syntax requirements or paradigms like say Rust lifetime annotations. Some of the rarer Nim idioms like `set[Enum]` being castable to a cint aren’t used.
But generally what you’d do in most C++ code works well in Nim, but with simpler syntax.
