Lunar is my attempt to distill 40 years of programming language experience into the "best" language I can come up with. I hope that this will bring some forgotten ideas back into the spotlight of public attention.

Document explaining the development of a bc/dc clone. Might be a good example to follow, if I ever make a public project.

Hy is a multi-paradigm general-purpose programming language in the Lisp family. It’s implemented as a kind of alternative syntax for Python.  http://hylang.org/
Compared to Python, Hy offers a variety of extra features, generalizations, and syntactic simplifications, as would be expected of a Lisp. Compared to other Lisps, Hy provides direct access to Python’s built-ins and third-party Python libraries, while allowing you to freely mix imperative, functional, and object-oriented styles of programming.
