Lisp!

Recently I started to get interested in lisp. I have looked at it before and appreciated its simplicity, but this time I decided to try and implement my own little dialect. The result is here and can execute a few simple operations.

• Quoting, e.g. '(+ 1 2) evaluates to (+ 1 2) rather than 3.
• The eval form, e.g. (eval '(+ 1 2)) evaluates to 3.
• The n-ary operators +, -, *, and /.
• The lambda form, e.g. (lambda (x) (* x x)).
• The macro form, which is similar to lambda except that its arguments are passed unevaluated.
• The with form, which works as shown in the example.

Be warned that the code for the interpreter is not pretty. Probably best not to try to read it.
