JsonLisp is a primitive Lisp-like language using JSON as its syntax. Be a real JSON programmer!
After installing JsonLisp, try it out in a built-in repl environment: :
$ python -m jsonlisp
{λ}> ["defproc", "fact", ["n"], ["if", ["<=", "n", 1], 1, ["*", "n", ["fact", ["-", "n", 1]]]]]
["lambda", ["n"], ["if", ["<=", "n", 1], 1, ["*", "n", ["fact", ["-", "n", 1]]]]]
{λ}> ["map", "fact", ["range", 0, 10]]
