Parentheses

Nujel uses the S-Expression notation as used by languages such as Lisp, Scheme and Clojure, but with one difference: Nujel defaults to using brackets instead of parentheses. This is mainly because brackets are much easier to type with a default US keyboard layout. You can still use parentheses if you must, since the two are completely interchangeable.

(+ 1 2)
3

Dotted pairs are also supported:

(car '(a . b))
a

(cdr '(a . b))
b

(car (cons 1 2))
1

(cdr (cons 1 2))
2

And as you can see Nujel uses car and cdr to access the first or rest parts of lists. To build a new pair you can use cons.
