I don't know the list of languages included in the book, but anyone interested should try out: - J: https://www.jsoftware.com/#/ you'll learn arbitrary dimension arrays, verb composition and more - Lisp: I don't know the right Lisp to recommend. Macros stand out as something to learn - Forth: I don't know the right Forth to recommend. The stack is an interesting metaphor - A constraint-based language: maybe https://www.minizinc.org constraints are super interesting Those are all practical languages -- none is esoteric just for the sake of strangeness. There are more of course.

Good choices. Add APL, Prolog, and Rebol.

  Hmmm. GP listed three languages which are not esoteric, and you've patted them on the back and shared three more which are not esoteric. Oops. Esoteric language =/= any non-mainstream language. Here's the definition from the esoteric programming language wiki, which is a lovely resource for anyone interested https://esolangs.org/wiki/Esoteric_programming_language https://esolangs.org/wiki/Esoteric_programming_language: > An esoteric programming language is a computer programming language designed to experiment with weird ideas, to be hard to program in, or as a joke, rather than for practical use.

    Ummm...APL, Prolog, and Rebol are extremely esoteric. Their share of total code out there has got to be like less than 0.0001% and their paradigms are considered extremely weird and not for general consumption . I don't agree with the definition of esoteric included above and by the original poster.

The right Forth is the one you write.

  In your Forth.

    And then you write a custom outer interpreter to create a DSL designed to write FORTH inner interpreters.

I don't think those languages would be "esoteric" in the meaning of the article (purposefully designed to be different for the sake of being different) but they are more like domain-specific languages designed to fit certain use-cases extremely well, and in doing so, depart from the traditional imperative model.

I would add an SMT solver like Z3. It can solve problems when they are translated into first order logic.

Racket is the canonical LISP (well, Scheme) to recommend to new users. https://racket-lang.org/ https://racket-lang.org/

  Yeah, as much as I love Common Lisp and prefer it to Scheme (despite learning Scheme first), the fact you can read the entirety of R7RS small in a single afternoon is, in my opinion, quite important in making the language approachable to beginners.

    If you wish, you can install a package to run R7RS small program in Racket. Just run in the commend line raco pkg install r7rs or search r7rs in the package manager inside DrRacket. It's not maintained by the core developers, but it pass all the test suit and if you ever find a bug and post an issue in github or in the discourse group, it will be fixed very soon. https://pkgs.racket-lang.org/package/r7rs https://pkgs.racket-lang.org/package/r7rs https://github.com/lexi-lambda/racket-r7rs https://github.com/lexi-lambda/racket-r7rs more info: https://github.com/lassik/racket-r7rs-example https://github.com/lassik/racket-r7rs-example

Forth would be neat on an RPN calculator. /random

Lisp is not esoteric. Emacs, Guix, AutoCad...
