```

## Examples

Arithmetic:

``` lisp

> + 1 2

3

> * 1 2

2

> * (+ 1 2) (- 10 8)

6

```

Lists:

``` lisp

> { 1 2 3 }

{1 2 3}

> head {1 2 3}

1

> tail {1 2 3}

{2 3}

> join {1 2 3} {5 6 7}

{1 2 3 5 6 7}

> eval {+ 1 2}

3

```

Variables:

``` lisp

> def {a b c d} 1 90 20 87

()

> a

1

> (+ b c)

110

```

Functions:

``` lisp

> fun {add-together a b} {+ a b}

()

> add-together 32 18

50

```

Macros (fun fact: 'fun' is actually a macro defined in the language):

``` lisp

> def {fun} (\ {args body} {def (list (head args)) (\ (tail args) body)})

()

> fun {my-function a b c} {* a b c}

()

> my-function 1 2 3

6

```
