Unlisp -- Ultra miNimal Lisp

Perpose

(TODO)

Unlisp uses list this language supported, because We have not to make lexer.

Example:

# (+ 1 1)
["+", "1", "1"]

Unlisp only supports types are Integer, String, Function, List. Yes, I know Lisp has more type, but It's no nessesary to make unlisp.

["type", "1"] # => Int
["type", "Hello, Unlisp"] # => String
["type", "+"] # => Function
["type", ["list" "1" "2" "3"]] => List

Unlisp only supports def keyword and fn. def means define variable, and fn is lambda like function.

(def <name> <body>)
(fn  <formal parameters> <body>)

Example:

["def", "x", "1"]
# fn closure
[["fn", "x", ["fn", "y", ["+" "x" "y"]]] "1"] "2"]
["def", "plus-one", ["fn" "x" ["+" "x" "1"]]]
