Just a note...
I just wanted to comment, since it has been several weeks since I posted here, that 3.0 is still developing.
The primary progress in recent weeks has been the completion of the first "environment". This is a wrapper around the embedded REBOL library kernel, with callbacks to the wrapper for OS specific functions (e.g. output to the console). This approach allows REBOL to be easily integrated into a wide range of programs including such things as web browsers and http servers.
I should note again that the more "quiet" things seem to be, the more is getting done. This is true for most types of software projects, not just REBOL.
