Simple function to stack elements on top of each others. Useful to create object stacks.

Installation
------------

[](#installation)

```
composer require innmind/stack
```

Usage
-----

[](#usage)

```
use function Innmind\Stack\stack;

$decorate = stack(
    static function(RequestHandler $handler) {
        return new ValidateRequest($handler);
    },
    static function(RequestHandler $handler) {
        return new Security($handler);
    }
);
$handler = $decorate(new MyRequestHandler);
```

The above example is equivalent to:

```
$handler = new ValidateRequest(
    new Security(
        new MyRequestHandler
    )
);
```

**Note**: the classes uses do not exist, they're only meant as an example.
