The work on Phobos v2 has been initiated which is a good thing. However, shouldn't D3 be developed alongside withe Phobos v2?
With Phobos v2 we have an opportunity to review what is needed in the D language and adjust accordingly. Right now we have a DIP process which has a high inertia by design. While this is good for a stable language, for new development we need a more disruptive platform in order investigate what works/what is useful with the D language. Where the maintainers/developers can play and investigate new ideas without the fear of destroying for the developers working with D2. Basically a long term testing ground.
It's really an opportunity we should take advantage of.
