Container::getInstance()->mapInstance('foo',new Foo());

isMapped($key)

get($key,$params = [])

if $key is mapped in container as an instance,return the instance;

if $key is mapped in container as a class,return the an instance of the class;

if $key is mapped in container as a closure,return the result of the closure;

if $key is not mapped in container,reflect $key and return the instance/result;

class Foo{

    private $bar;

    }

    public function getBar(){

$container->mapInstance('bar',677);
$container->map('sum',function(Foo $foo,$inc){
    return $foo->getBar()+$inc;
});

$foo = $container->get(Foo::class);
/* @var Foo $foo */
echo $foo->getBar();
//result is 677

$foo = $container->get(Foo::class,['bar' => 688]);
echo $foo->getBar();
//result is 688;

echo $container->get('sum',['inc' => 100]);
//result is 777
