The fact that the anonymous class syntax defines a class *and* immediately
constructs an instance is quite annoying.
For one, this is quite incompatible with DI containers' ability to resolve
constructor arguments.
Lets say you DI container can register a named component by merely
referencing a class that uses constructor injection - so lets say this
works:
class MyController {
public function __construct(MyService $service) {
// ...
}
}
$container->register("my-controller", MyController::class);
Now I want to register an anonymous class, for example as part of an
integration test-suite, which is common enough:
$container->register("my-controller", new class {
public function __construct(MyService $service) {
// ...
}
});
This doesn't work, because you're expected to actually pass the constructor
arguments immediately - because you can only define an anonymous class
while immediately creating an instance.
What I really want is just an anonymous class - not an instance, so:
$container->register("my-controller", class {
public function __construct(MyService $service) {
// ...
}
});
The question is, what would a class expression without the new keyword
evaluate to?
Since we normally reference classes with just a class-name, I guess I'd
expect a string, like you'd get from the ::class constant.
Any hope for something like that?
