"I am not sure but I think in R3 everything except very narrow core of language will be open sourced." I am not sure if that would be very attractive to hackers. Why would anyone want to use a non open source language these days? Making a language closed source (even in parts) these days is to guarantee that it remains a niche language (unless it has been lucky enough to have a lot of pervasive legacy code, which Rebol certainly doesn't). I, for one, would never choose a closed source language for one of my projects.
