Study about expressiveness of programming languages

This has been around for a year, but never posted here: http://redmonk.com/dberkholz/2013/03/25/programming-languages-ranked-by-expressiveness/ Notice that the only 2 languages which rank higher than Rebol are DSLs for performing specific and limited tasks.

I like secrets, and I'm really liking Rebol.

I think there's a lot of that in this community.
