A tree-walking Lisp interpreter written in Gleam!

It features:

• Ints with +, -, *, and /.
• Bools with not, and, and or.
• Comparison with =.
• Lists with empty, cons, car, cdr.
• Closures with lambda.
• Global variables with define.
• Local variables with let.
• Flow control with if.

Usage

import glisp

pub fn main() {
  glisp.eval("(+ 1 2 3)") //=> "6"
}

Caveats

I wrote this on a transatlantic flight on a day that involved no sleep so expect bugs and other curiosities.
