Actually, I learned by programming assembly for a long gone platform, 25 years ago. I have learned Python already after many years programming in C, Perl, Java and Common Lisp, professionally. Experience with Lisp gave me a certain way of looking at programming languages. Rather than "oh, how fun!", I am more like "let's see which subset of Lisp it implements". The only really interesting language in recent years that I have learned is Rust which truly does something new and it recalibrated my thinking about utility of making further subsets of Lisps. It seems there is still a lot of possibility for improvement from the language standpoint, and that it is possible that a lot of improvement may come from restricting the developer from doing certain things rather than giving unrestricted freedom.
