$key not available in @each directive

[W0lfw00d]

Describe the bug
When using the @each directive the $key/index isn't available.
The documentation states:
'The key for the current iteration will be available as the key variable within your view partial.' But when you try to use $key in your template it's undefined.

To Reproduce
In your main template:
@each('partial.car', $cars, 'car')
and inside `partial/car.slice.php':
{{$key}}
Expected behavior
print the key/index

Versions (please complete the following information):

• PHP: 7.2
• CodeIgniter: 3.1.9
• Slice: 1.3.0

First of all, thanks for trying Slice Library!

Well, the third parameter of @each directive is the name of the variable. It is actually, a variable variable!

Could you please, try using inside partial/car.slice.php like this:
{{ $car }}

Sorry for the poor explanation in the docs! As soon as you can test it, lemme know, ok?

Well, thank you for making it! 😃
I would have hated to write all those templates with plain php. Brr...

I understand the array value example and that works perfectly. :)
But as I read the documentation it seemed like it was possible use the key of the array. Like in the follow example (which is my work around for now):

@foreach($cars as $key => $car)
	@include('partial.car', ['car' => $car, 'key' => $key])
@endforeach
@if(!$car)
	@include('partial.empty')
@endif
