Allows traversal of objects and arrays with a simple string syntax. Extracted from Peridot's matcher library: Leo.

'name' => 'Brian',
'hobbies' => [
'reading',
'programming',
'lion taming'
],
'address' => [
'street' => '1234 Lane',
'zip' => '12345'
]
];
use Peridot\ObjectPath\ObjectPath;
$path = new ObjectPath($data);
$reading = $path->get('hobbies[0]');
$zip = $path->get('address[zip]');
// the result of get() is an ObjectPathValue instance
$value = $reading->getPropertyValue();
// The syntax also works for objects and nested structures
