    Moldable Live Programming for Clojure

    Clerk is a notebook library for Clojure that enables interactive, reproducible, and version-control-friendly live programming.

    Hy

    Hy

    A dialect of Lisp that's embedded in Python

    ...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. The first thing a Python programmer will notice about Hy is that it has Lisp’s traditional parenthesis-heavy prefix syntax in place of Python’s C-like infix syntax. As in other Lisps, the value of a simplistic syntax is that it facilitates Lisp’s signature feature, metaprogramming through macros, which are functions that manipulate code objects at compile-time to produce new code objects, which are then executed as if they had been part of the original code.
