I have been using Nim for everything lately. If I have a problem I would typically write a shell script for, I'll use Nim with nimcr. If the problem expands beyond a single file, I'm in a good spot to create a project and have production-ready solutions.
The interoperability with other languages makes it a safe choice if I find I need to integrate into an existing project. I'm never coding myself into a corner.
I've never used a language as versatile as Nim. It's my secret weapon at work. I want more people to use it, but I do like my advantage...
