Peter, we all agree that work like Robin’s data structure improvements is vital to the language and community. We have no intention of making that work by him or anyone else impossible or even very difficult. The reason that there is a lack of clarity around how this will work is because we don’t know how it will work, exactly. I don’t think this is an unreasonable place to be in the process because, as has been said many times, the alpha isn’t even finished. Even so, Evan has already been working with Robin to see how his goals can be achieved without disrupting Robin’s process. The hypothesis is that if Robin can do the work he wants to do then other people should be able to do similar work as well. I’m sorry there isn’t more information, but, once again, the development process is still ongoing.
