Oh its Turing complete alright:
It would be more apt to say that programmers use dozens of 'languages'
(in the sense of notation) that are very far up/down from Turing
- regular expressions and parsing tools like yacc are less than Turing
- specification langauages like Z/UML are more powerful than Turing
machines in that one can specify unimplementable programs
So when I say 'language' strictly I should say 'programming language'
If (something like) Charity succeeds *as a programming language* then
it will be a significant change in how we view programming. As a thought experiment that is interesting but I would be skeptical…
