I agree with this sentiment.

I try to learn the basics of new programming language regularly and write a small lisp alike interpreter in it and give myself a maximum of 2 days working on it. It covers things like string handling, regexp, recursion, lambdas, garbage collection, ... and run them through a tiny test suite.

In Python and JS, it was easy to do it and the code was still very readable. In C++, the language I earn my money from, I had a bug I was not able to fix within the given time frame, happening just with gcc not clang, assuming some undefined behavior. In C, I was able to add my own garbage collector with muss less work than I expected ... but

Nim really impressed me, it really felt almost like I wrote it in Python, but an executable which run on its own and being quite a bit faster.

Working mostly in the embedded world, where ecosystem matters somewhat less. If any employee ever would give me a chance to choose a language myself I would definitely try to write a first prototype in Nim.
