Annotation extension with CONDYN

[Jeremy Barrow]

Hey everyone,
As I was working on something relating to annotations,
I realised we still use the typical pattern of using a class or some other
constant to refer to specific functionality.
With things like MethodHandles and a lot more recently CON DYN surely it's
possible to embed a lot more into an annotation?
Is there any specific technical restriction, because I would love being
able to do something like:

Right now we have to do something like:
@Annotation("onBefore"), and then do the necessary things behind the scenes.
This does raise questions such as being able to enforce signatures, etc,
but I don't think that's a problem as it's no different to what it was
before, and it's effectively the same as, say, accepting a MethodHandle as
a parameter.

Cheers,
Jeremy.
