Some proposed ways of implementing scoped services:

1. Create scopes at the time of usage:

   import { Elysia } from "elysia";
   import { container } from './dependencies';
   
   const app = new Elysia()
     .transform(({ request }) => {
       const scope = container
         .createScope({ request: () => request })
         .register("authService", createAuthService);
       return scope.resolveAll();
     })
     .get("/session", ({ authService }) => authService.getSession());

2. Define the entire dependency tree in one place, and just create the scope when needed:

   export const container = createIocContainer()
     .register("db", Database)
     .defineScope<{ request: Request }>(
       "request",
       (scope) => scope
         .register("authService", AuthService })
         .register("userService", UserService })
     );

   const app = new Elysia()
     .transform(({ request }) => container.createScope("request", { request }))
     .get("/session", ({ authService }) => authService.getSession());

Both methods would support nested scopes and multiple other scopes.
