@gosha I started with some extracurricular Scheme during university on the recommendation of a professor who taught Java, but would have preferred to have been teaching Scheme or Smalltalk. Then, I used Clojure at work for some data cleansing and loading pipelines, for which I think it's pretty much perfect. Finally, Emacs, then Smalltalk, introduced me to interactive development, I became fascinated with the Lisp machines, and satisfied with Common Lisp with SBCL and SLIME.
