I had interest in Rebol and Red, but lost it. Lost the interest because of what you mention, but also because building algorithms with it imply a big cognitive load for me. Since then, I'm very happy with TCL, one of the inspirations for Rebol. Its syntax is regular, it's a professional tool, conservative, i.e. doesn't break code at each new release, has great GUI with Tk, and many other advantages.
