I really love D, it's one of my favorite languages. I've started implementing a vim-like text editor in it from scratch (using only Raylib as a dependency) and was surprised how far I was able to get and how good my test coverage was for it. My personal favorite features of D:
* unit tests anywhere, so I usually write my methods/functions with unit tests following them immediately
* blocks like version(unittest) {} makes it easy to exclude/include things that should only be compiled for testing
* enums, unions, asserts, contract programming are all great
I would say I didn't have to learn D much. Whatever I wanted to do with it, I would find in its docs or asked ChatGPT and there would always be a very nice way to do things.
