Glisp - a small Lisp implementation in Go [WIP]

Motivation

Fun.

Examples

Value declaration

(defvar i 64 "just an int equal to 64")
(print i) // 64

Defining a collection

(defvar int-list '(1 2 3)
    "a list of ints")  // list
(defvar int-vector [1 2 3]
    "a vector of ints") // vector

Function declaration

(defun main (args)
    "the main function"
    (print (len args)))
(main '("one" "two")) // 2

Function call

(print (* 5 5)) // 25
