Though I agree on the power of generators and projections IMHO it significantly raises the complexity of solutions. And I'm not sure how popular is the usage amongst the community, we could make a poll.

Moreover, I met the opinion that some powerful features of IRIS like indirection are completely useless and dangerous (I disagree of course as a fan of indirection).

I'm 100% for the usage of powerful things if we can keep readability and maintainability.

And of course, people will use the technology immediately once see the obvious value.
