Don't quite understand the section "Don't write to global functions"

[panigrc]

I don't understand how the

// config.php
return [
    'foo' => 'bar',
];

How is the array being used ?

I agree. It doesn't look very clear.
The idea was this:

$config = include 'config.php';

$configuration = new Configuration($config);

Ok Thanks for clarifying that ! 👍

@panigrc Please take a look, my PR #97.
This example became more clear?
