I was commenting on posts referring to Nim as having multimethods, which it only barely does by the skin of its' teeth, not so much judging multimethods; nonetheless, I'll bite.
You may think Julia's multimethods are inferior, clearly the Julia designers [disagree](https://www.youtube.com/watch?v=kc9HwsxE1OY&ab_channel=TheJuliaProgrammingLanguage). Have you tried Julia for anything significant, even a few hundred LOC? I did, a few years ago, and I agree with Stefan Karpinski, there is a surprising amount of reuse because of multiple dispatch. Does multiple dispatch belong in a statically typed systems level programming language like Nim? My gut says 'no', but I'm open minded. I think a better approach for Nim would be to adopt a more traditional OO system, with the goal of facilitating interoperation with C++, in the same way that Swifts' design was influenced by the goal of porting from Objective C.
