automatic mixin in classes
I've stumbled upon this numerous times and I wish I could automate this
somehow.
The idea is to have some mixin templates mixed into classes automatically
when they inherit from some base class.
For instance, advanced RTTI methods, which analyze the enclosing class at
compile-time.
Unfortunately, AFAIK, there's no way of doing it automatically and one
needs to both derive from a certain class and mix in a certain mixin
template manually.
Is there a way to avoid the boilerplate and have it done automatically?

Does this give you any ideas on how to solve your use cases:
https://github.com/csauls/zeal.d/blob/master/source/zeal/base/controller.d
https://github.com/csauls/zeal.d#controllers
https://github.com/csauls/zeal.d/blob/master/source/zeal/http/router.d#L93

I had this need several time too. But I don't think this should be a 
functionality added in D at this point.

This is typically AOP stuff and it is much more interesting for D to 
think about how to integrate the whole AOP concept instead of hacking 
around each use case.

I don't see anything related to this issue.

Re: automatic mixin in classes
Yeah, I know. Currently bug fixes are way more important then new features
and this one really really looks like a dirty hack. But the problem it
solves is very real. I honestly don't know what to do about it.
