In the case of a Mixin that would be entirely valid. When implementing
interceptors things
get more complicated though. Its true that all of the interceptor method
bodies could be
merged into the original method, it would just make the weaving more
complicated.
It is avenue worth exploring though.

Ok, that might throw a spanner in the works. But I'm not sure if we really
need an AST
for the entire code base, as long as we can resolve references it ought be
ok.
I think we can make it work on a per-compilation-unit basis to be honest.
