Snippets and programmatically creating new classes

[Tiark Rompf]

Hi all,

I've been playing with Graal a little since you guys came visiting EPFL in March.
I like the idea of Snippets and I was wondering, what is the preferred way of adding and
deploying custom Snippets that are specific to a particular application or library? 

Also, is there a suggested way of programmatically creating new classes or methods? 
For example, I would like to implement something similar to 
java.lang.reflect.Proxy.newProxyInstance, creating an object on the fly that
implements a bunch of interfaces, where the method bodies are created directly using
Graal IR. Is there an API for this or would I still need to produce some byte code 
and pass it through a class loader?

Cheers,
