The goal should be to make a language less noisy, not more. We need less symbols, not more. =) Less is more. Less types of parenthesis, less commas, less semicolons.
If we can only incorporate the list-comprehension into a Lisp/Scheme language without creating a terrible mess, this is good enough, and one should stop here.
Python3 is the best thing that could happen to *comprehension syntax. Everything else, especially Clojure, is much worse, because it breaks a great pair of clarity and beauty. ^_^
I will relocate to Sweden soon, but can't speak Swedish - that is the problem. I'm engineer with 15+ years in the field.
