Correct. In Solar, it is used always and only; that is, every
constructor for every class is identical:
public function __construct($config = null) { ... }
It helps to standardize configuration of instances and aids greatly in
Dependency Injection and Service Location. I call this a "universal
constructor." I don't know if this pattern has been cataloged anywhere.
