Lewis is a tiny dialect of Lisp that interoperates with Go (à la Clojure).
Make sure you have Go installed, then clone the repo:
$ git clone https://github.com/mion/lewis.git
Setup the workspace (Go environment variables):
$ cd lewis
$ source setup_workspace.sh
Build it:
$ sh build.sh
Start the REPL:
$ lewis
You can import and use Go packages as such:
(import math/big)
(define x (NewInt 123))
(define y (NewInt 456))
(define z (NewInt 0))
(z Exp (x y nil)) -- From Go's "math/big": func (z *Int) Exp(x, y, m *Int) *Int
