IF Rebol would be properly modularized, e.g. much earlier discussion about one and only
/Core.exe, others as loadable components, or just ability to 'package appropriate components
into
one .exe, even compiler could be separate component, no?

whatever in rebol-like style, whatever making it faster ... :-)

sounds interesting, is it achievable? What would such "dialect" look like, what exactly
should be
its purpose? Could you explain a little bit, please?
