Since I have quite a few projects and I actually do not need any other language for what I do at the moment, I do not plan on learning a new language... is what I want to say.
Guess what? I fell for Rust. I already love C++, but I can see its shortcomings and how Rust tries to improve on them. I am working on a game, and I want to develop at least parts of it in Rust and compile them to static libraries which I can link into my C++ program.
Apart from Rust, people always talk about how Smalltalk makes you a better developer. So I want to give it a try, too. But probably not in the next few days...
