Spiral already supports DI containers based on *Scope *(like "per request"
injections). Symfony, if I’m not mistaken, does too.
Spiral introduces a restriction to ensure correct handling of Scope
dependencies: they cannot be mixed with regular dependencies. If a Scope
dependency is needed inside a regular dependency, then (using the same
approach that Larry already showed), it should be done through an
additional interface:
```php
final class UserScope
{
public function __construct(
private readonly ContainerInterface $container
) {
}
public function getUserContext(): ?UserContext
{
// error checking is omitted
return $this->container->get(UserContext::class);
}
public function getName(): string
{
return $this->getUserContext()->getName();
}
}
```
At the beginning of a request, Spiral initializes a memory area with Scope
dependencies, so it can be said that it is already prepared to work with
coroutines with minimal modifications.
