Hi,
I decided to give a try idea of implementing Scala counterpart of java.lang.reflect.Proxy functionality. Here's the result of quick hacking: http://goo.gl/5AmJd
Basically, the idea is to provide similar functionality to Proxy but using Scala reflection API types intead of Java ones. There are lots of benefits including proper handling of fancy method names like bar_!.
I think use of Proxies in Java is popular usecase for reflection and we provide our API for it too. Thoughts?

Re: Scala proxy (first try of Scala's reflection API)
Wouldn't it be preferable to use Any in the signature of invoke, rather than Object?

I'd need to put AnyRef because Array (for args) is invariant. In principle, you are right. It's better to stick to Scala types.
Corrected.
