-A light lisp written in C++

-## Why write a lisp?
-
-Lisp is one of those niche, beautiful languages that people only really use to either
-
-1. Write a lisp interpreter
-2. Show off how "code is data!!!"
-
-_So why add to the list of infinite lisp interpreters?_
-
-The answer is simple: _**I'm bored out of my mind in quarantine.**_ If you were looking to find out why _this particular_ lisp is special, you're fresh out of luck. 
-
 
 ## Syntax and Special Forms
 
-Like every other lisp, this language uses s-expressions for code syntax and data syntax. So, for example, the s-expression `(print 5)` is both a valid code snippet, and a valid list containing the items `print` and `5`.
-
-When the data `(print 5)` is evaluated by the interpreter, it evaluates `print` and `5`, and then applies `print` to `5`. 
-
-Here's the result.
-
-```lisp
->>> (print 5)
-5
- => 5
-```
-
-That's super cool! But what if we want to define our own functions? _We can use the builtin function `defun`!_
-
-```lisp
-; define a function `fact` that takes an argument `n`
-(defun fact (n)
-  (if (<= n 1)
-     1
-     (* n (fact (- n 1)))
-   ))
-```
-
-Thats awesome! But did you notice anything different about the `defun` function? _It doesn't evaluate its arguments._ If the atom `fact` were evaluated, it would throw an error like so:
-
-```lisp
->>> fact
-error: the expression `fact` failed in scope { } with message "atom not defined"
-```
-
-This is known as a special form, where certain functions "quote" their arguments. We can quote things ourselves too, but the language _automatically_ quotes arguments to special forms itself.
-
-If you want to "quote" a value yourself, you can do it like this.
-
-```lisp
-; quote the s-expression (1 2 3) so it's not evaluated
->>> (print '(1 2 3))
-(1 2 3)
- => (1 2 3)
-```
-
-As you can see, quote negates an evaluation. For example, whenever the expression `''a` is evaluated, it becomes `'a`. This can be useful for when you want to write long lists of data or variable names without wanting to evaluate them as code.
-
 |Special Form|Argument Evaluations|Purpose|
 |:-|-|-|
 |`(if cond a b)`|`if` only evaluates its `cond` argument. If `cond` is truthy (non-zero), then `a` is evaluated. Otherwise, `b` is evaluated.|This special form is the main method of control flow.|

 ## Examples
 
-Here are some example math-y functions to wrap your head around.
-
-```lisp
-; quicksort
-(defun qs (l)
-    (if (<= (len l) 1)
-        l
-        (do
-            (define pivot (first l))
-            (+
-                (qs (filter (lambda (n) (> pivot n)) l))
-                (list pivot)
-                (qs (tail (filter (lambda (n) (<= pivot n)) l)))
-            ))
-    ))
-
-; decrement a number
-(defun dec (n) (- n 1))
-; increment a number
-(defun inc (n) (+ n 1))
-; not a bool
-(defun not (x) (if x 0 1))
-
-; negate a number
-(defun neg (n) (- 0 n))

-; is a number positive?
-(defun is-pos? (n) (> n 0))
