During implementation of Macros 1.1 one thing was not ported compairing to compiler plugins: ability to specify
derive attribute on traits.
I can see following use cases for derive-on-traits:
- mocking (used by my library)
- stub/proxy generation for RPC, REST services, etc
- wrappers generation (which may log each call or wrap it with lock, etc)
It was suggested to revive this ability as unstable feature, my question is: what should I do to ensure this is implemented, maybe create an issue, or write RFC?
