Re: [weld-dev] Automatic non contextual injection using bytecode instrumentation

I just had an idea for something that I think would be rather cool, and allow objects created using new to be injected automatically. Conceptually it would look something like this: @AutoInject public class AccountService { private final Account account; @Inject private PaymentProcessor paymentProcessor; AccountService(Account account) { this.account = account; } public void doPayment(double amount) { paymentProcessor.processPayment(account, amount); } } We could then create the object using new and the fields will still be injected: AccountService a = new AccountService(account); a.doPayment(10); To implement this will require a javaagent, which will modify the bytecode of @AutoInject annotated classes as they are loaded, so that the constructor bytecode looks up the values to inject and sets the injected field values appropriately. Would this be something that is worth putting into weld extensions?
