Auto class loader, similar to php. for lazy instantiation of objects

[JhulFramework]

In My Application I just want to register classes and instantiate them only when needed. it will improve performance of app.
Please implement this if it is possible.

Take a look at the section 'Lazily loading a library' in the language tour. Loading a 'deferred' library may not be exactly the same thing as 'registering and instantiating a class', but the deferred library mechanism was created in order to obtain fast startup times in return for some explicit management of the actual time where a library is loaded.

PS: This mechanism was considered important for the web platform, but a similar case wasn't made for the VM; so on the VM you will be able to use the code for deferred libraries, but the loading won't actually be deferred (check out #33118).
