$container->set(Foo::class);

$instance = new Foo(new Bar);

// this:
$container->set(Foo::class, $factory = null, $instance);

// is the same as this:
$container->singleton(Foo::class, $instance);

// this will trigger a call to ReflectionContainer::resolve() when Foo is requested:
$container->singleton(Foo::class);

// this will invoke the given anonymous function when Foo is requested:
$container->singleton(Foo::class, null, function () use ($bar): Foo {
    return new Foo($bar);
});

// this will invoke the given callback immediately:
$container->singleton(Foo::class, null, function (): Foo {
    return new Foo(new Bar);
}, true);
