# ANSI Common Lisp is a mess
|
||
|
|
|
||
|
|
Function names were written by a monkey
|
||
|
|
|
||
|
|
(terpri) <- meaning terminate print line
|
||
|
|
|
||
|
|
(princ) <- why not (print)?
|
||
|
|
|
||
|
|
## Variables
|
||
|
|
|
||
|
|
In [Scheme](https://kill-9.xyz/harmful/software/scheme) you can declare functions and variables with (define)
|
||
|
|
In common lisp. You can use (defparameter) (defvar) (defun) and probably much more.

;; scheme
|
||
|
|
(define x 3)
|
||
|
|
< x
|
||
|
|
> 3
|
||
|
|
(define x 4)
|
||
|
|
< x
|
||
|
|
> 3
|

;; ANSI Common Lisp
|
||
|
|
|
||
|
|
(defvar *x* 3) ;; * are optional though
|
||
|
|
< *x*
|
||
|
|
> 3
|
||
|
|
(defvar *x* 4)
|
||
|
|
< *x*
|
||
|
|
> 3
|
||
|
|
(defparameter *x* 4)
|
||
|
|
< *x*
|
||
|
|
> 4

Common Lisp (and any other LISP programming language) is fun to use. But can get easily confusing.
