Can someone please advise me on how to donate money to help Ola? There's a relevant web site but it hasn't been updated for a long time - http://freeolabini.org/en/
Not enough of them do, I agree, but some of the Modern Monetary Theory people do. E.g. Mark Blyth (some very entertaining talks on youtube), Stephanie Kelton. Also political economists do and always have, I believe. (IANAE, and in fact I'm not certain that Mark Blyth is an MMT person, but I thought I'd get the ball rolling.)
TCL is kinda similar to Rebol in some ways but in other ways it's the opposite of Rebol, because in TCL everything is a string (although it can ALSO have another type, thanks to clever shenanigans). (You probably knew this!)
I've tried it with fish and found that, for me, it didn't add much and wasn't worth the switch, but it is arguably slightly better than fish's built-in history; so I'd say only bother if you particularly love learning new things of this type.
