By no means I'm not an expert in Nim and have not yet reached 10k LOC I came from C# background and very happy with switching to Nim. So I will compare my feelings with C#
* Diversity ++ I think Nim is great in any domain. It's cool that you don't need to switch between different languages to do stuff. Templates and macros helps a lot in domain specific areas. It's normal in gamedev to have engine side on C++ and scripting side on C#/Lua/whatever. * Mental load -- Although it's joy to write in Nim and it gives so much freedom ( I'm fine with that ) that it's harder then in C# to follow strict guidlines. * Code visibility, info hiding, import/export -- After C# it's looks kinda naive. The biggest issue is that while technically you can hide some parts of the library from user it's inconvenient. There is no internal namespace scope where I can easily separate lib functionality from the users code. Again, Nim is not C#, I understand that, but particulary organization of code in C# feels easier. I spend a lot of time thinking how to organize stuff in Nim ( heck, more time then actually writing the code XD ) This is the biggest issue for me at the moment. In overall Nim is outstanding for me. All problems are solvable and I look at them as challenges. But I know at least one C# programmer that dropped learning Nim because of last issue I described ( No internal/protected scope )
