    Common Lisp lazy sequence library

    I learned Common Lisp before I learned Python, so I am not impress by generators, normally you can emulate them using closures, at least the ones I've used. Lazy evaluation also is a good way to obtain that kind of functionality. If you want to know the how this is a good article. He refers in that article to his library (slow-jam), which does several interesting things. You can also take a look at this.

  • picl

    mmh this library seems rather good: https://github.com/anlsh/picl (but there are more, like the built-in Iterate feature. You probably found https://stackoverflow.com/questions/32956033/is-there-a-straightforward-lisp-equivalent-of-pythons-generators)

  • quid-pro-quo

    A contract programming library for Common Lisp in the style of Eiffel’s Design by Contract ™.

    Here's a Lisp library for contracts: https://github.com/sellout/quid-pro-quo (not saying this is what ADA has ..)

  • mgl-pax

    Exploratory programming environment and documentation generator.

    Ada has contracts also. I think possible to implement. https://github.com/melisgl/mgl-pax which I use for CLOG does a good job of documenting specs and gives me some ideas about how to go about it and same with generic functions themselves. At some point all apply myself to it.

  • liz

    Lisp-flavored general-purpose programming language (based on Zig)

  • coalton

    Coalton is an efficient, statically typed functional programming language that supercharges Common Lisp.

    What about Coalton, is it missing something, not "powerful" enough? https://github.com/coalton-lang/coalton/
