Seems like a good Swiss Army Knife-like addition to the shell script (reminds me of awk as well). It would be interesting to keep it that simple (not another Perl)
Rebol was known for its small set of moving parts and behaviors but with a lot of depth and flexibility with them. I've added some moving parts with left to right code flow, but I still hope it's a limited set that fits well together. I am adding new behaviors very conservatively now, and I will remove some. Thanks for heads up about Perl! ;)
