Purpose of this Rebol fork is to push the origial Carl's source to be usable at least like Rebol 2, but keep the source code clean and project easy to build.
You may want to check Ren-C and Red projects, if you are looking for other Rebol like languages.
And or Shinxin's fork, which is much more ahead than this fork as it contains modifications from Atronix and Saphirion. But with a cost that the code structure is not clean as the original.
