Sven Linstaedt commented on CDI-10:
-----------------------------------

For the purpose of reading class metadata (fields, methods, annotations, ...) of bean instances one can also make their Beans (and maybe also AnnotatedType, so other frameworks benefit from metadata being overridable) able to lookup. E.g. via BeanManager like BeanManager#lookupBeanOf(T proxy), so their is no need to unproxy bean references just for being able to access their java type.

> There are occasions when it would be useful to access a bean instance directly from a proxy. This could be achieved by making all proxies assignable to an interface (say BeanProxy) that provides a getBeanInstance() method. 
> Client code that needs access to the actual instance can check if the object is assignable to the BeanProxy interface and then call getBeanInstance() to get the actual instance if required.
> This is something that is probably more useful to extension writers than the end user, but there have already been a few requests on the weld forum about this so it is probably worth considering.
