Wrapping object for scalar (or null) only
=========================================

PHP provide scalar type hinting since [PHP 7.0](https://wiki.php.net/rfc/scalar_type_hints), but no native function is able to protect us against value lost on cast.

For that reason, if we want to be sure about scalar type, a scalar converter and optionally a type-checking class are the only chance.

Warning: The converter and so the wrapper class does not cast null - it remains null.
