### Typed handlers

Typed handlers are handlers that have a specific type for the request and response payloads.

```go
    // Create a typed handler.
    handler := func(ctx context.Context, p *Payload, in <-chan *Req, out chan<- *Resp) *RemoteErr {

                Class<? extends Annotation> annotationType = a.annotationType();
                if ("org.eclipse.sisu.Typed".equals(annotationType.getName())

                        || "jakarta.enterprise.inject.Typed".equals(annotationType.getName())) {
                    try {

/**
 *
 * Note: uses @Typed to limit the types it is available for injection to just ModelProcessor.
 *
 * This is because the ModelProcessor interface extends ModelLocator and ModelReader. If we
 * made this component available under all its interfaces then it could end up being injected
 * into itself leading to a stack overflow.
 *
 * A side effect of using @Typed is that it translates to explicit bindings in the container.
