"In 1988, Sassenrath left Silicon Valley for the mountains of Ukiah valley, 2 hours north of San Francisco. From there he founded multimedia technology companies such as Pantaray, American Multimedia, and VideoStream. He also implemented the Logo programming language for the Amiga, managed the software OS development for CDTV, one of the first CD-ROM TV set-top boxes, and wrote the OS for Viscorp Ed, one of the first Internet TV set-top boxes."
Right? And I think that's what keeps bringing me back to REBOL, and thus Red. They don't appeal to me on the face of them. Like, the code examples look interesting but in a "magical" kind of way that strikes a little bit of fear into my engineering heart. But with that kind of pedigree, I can't dismiss the ideas. If Sassenrath came up with it, I bet there's a kernel of awesomeness inside.
I suspect a lot of the magic will fall away after realizing the block data structure (the square brackets) are pretty close to a Lisp list. And just like in Lisp, they're used for both code and data. One big difference is words are evaluated by default instead of just the first word in a list, so there's nowhere near as much nesting, and whenever an expression ends the next one can begin with no delimiter (but use newlines for legibility).
What a legend!
