## :muscle: Example :muscle:
### :one: S expression **parser**
As expressions
```haskell
>>> print [parse|123|]
AtomInt 123
>>> print [parse|sugar|]
AtomSymbol "sugar"
>>> print [parse|(1 2 3)|]
Cons (AtomInt 1) (Cons (AtomInt 2) (Cons (AtomInt 3) Nil))
```
As patterns
```haskell
>>> case AtomInt 123 of; [parse|123|] -> "good"
"good"
>>> case AtomInt 000 of; [parse|123|] -> "bad"; AtomInt _ -> "good"
"good"
>>> case Cons (AtomSymbol "x") (Cons (AtomInt 10) Nil) of; [parse|(x 10)|] -> "good"
"good"
```
As types (compile time calculations)
```haskell
>>> fromSing (sing :: Sing [parse|10|])
AtomInt 10
>>> fromSing (sing :: Sing [parse|konoko|])
AtomSymbol "konoko"
>>> fromSing (sing :: Sing [parse|(1 2 3)|])
Cons (AtomInt 1) (Cons (AtomInt 2) (Cons (AtomInt 3) Nil))
```
### :two: S expression parser + **preprocessor**
```haskell
>>> [parsePreprocess|sugar|]
AtomSymbol "sugar"
>>> [parsePreprocess|'10|]
Quote (AtomInt 10)
>>> [parsePreprocess|(quote 10)|]
Quote (AtomInt 10)
```
### :three: S expression parser + preprocessor + **evaluator**
```haskell
>>> [zurae|10|]
10
>>> [zurae|(print 10)|]
10Nil
>>> [zurae|'10|]
AtomInt 10
>>> [zurae|sugar|]
:12:8: error:
• Maru.QQ.zurae: an error is occured in the compile time: EvalException: "A symbol 'sugar' is not found"
• In the quasi-quotation: [zurae|sugar|]
```
