Since you're a Vim user like me: I've found Emacs Lisp a good way to accidentally learn Lisp! Like there are many Lisps, there are many Vims. Spacemacs is a Vim for Emacs or inside Emacs: https://www.spacemacs.org/ https://www.spacemacs.org/ It's quite powerful. And it can be argued that Emacs is highly extensible - because it's written in a Lisp. Looking under the hood and hacking on the editor is a lot of fun and very informative. And also horrible and bad. But in a good way! And almost completely unrelated: I very much enjoy the Structure and Interpretation of Computer Programs book and online lectures: https://ocw.mit.edu/courses/electrical-engineering-and-computer-science/6-001-structure-and-interpretation-of-computer-programs-spring-2005/ https://ocw.mit.edu/courses/electrical-engineering-and-compu... The video lectures were recorded in 1986!: https://ocw.mit.edu/courses/electrical-engineering-and-computer-science/6-001-structure-and-interpretation-of-computer-programs-spring-2005/video-lectures/ https://ocw.mit.edu/courses/electrical-engineering-and-compu... And they're still amazing. (But people all think very differently and what works for me may not be your cup of tea!)
