We can use the Service Container as a Registry by binding an instance of an object in it and get it back when we'll need it:
// Create an instance.
$john = new User('John');
// Bind it to the service container.

// ...somewhere and/or in another class...
...
We can bind a class as a Singleton:
public function register()
{
App::singleton('my-database', function()
{
return new Database();
});
}
This way, the first time an instance of 'my-database' will be requested to the service container, a new instance will be created. Al...

When the destructor for std::thread is invoked, a call to either join() or detach() must have been made. If a thread has not been joined or detached, then by default std::terminate will be called. Using RAII, this is generally simple enough to accomplish:
