Does anyone else find CoffeeScript insufferably unreadable? Why take a basically nice-looking language like JavaScript and bathe it in special forms?
I do think, however, that many of the ruby-ish syntax tweaks are more expressive once you get used to them. That is, I learned C-like syntaxes before I learned ruby and I still find I'm able to parse ruby-like code much faster than c-like code. There is more to learn in terms of symbols, constructions, but once you know them, they communicate more information faster.
