README
======
This is my Lisp implementation. Compiling the project results in a REPL where
you can execute minimalistic Lisp code. I'm saying minimalistic because there's
nothing but lists, quoted lists, symbols and quoted symbols!
There's no extra syntax for defines, lambdas, etc. Lazy evaulation is done by
passing around quoted expressions.
Right now, it supports dynamic scoping. This is going to change.

Building
--------
Requires bison, flex and gcc:

./make

Examples
--------
(define 'name 'peter)
(print name)
peter
(define 'my_print '((x) (print x)))
(my_print 'hello)
hello
('((x) (print x)) 'hejsan)
hejsan

(define 'or ((first 'second) (if first first (eval second))))

Root environment
----------------
The root environment consists of these functions (which can be used everywhere):

define NAME VALUE
  binds a value in the current environment to a value (remember, code is value)
  
print VALUE
  prints the value of a symbol to stdout
