True, but the article is very short, it will be featured more like a post. It's by far not a tutorial; the examples aren't even explained. > Recursion is no special feature of Ruby. > Almost every language has it. I'd like to include it although it's not an exclusive feature; IMHO, it still shows that Ruby code can be elegant, >>class Digits_to_english < String >> def to_e >> self.scan(/\d/).map do |digit| > I don't get the point here. Why do you call it "Objects". d2e is an object, of a class that's implemented just above. Thanks also for you snippets :) Sorry to not include them; it's a very short article, and by far doesn't try to cover most of the great features and concepts; just some of the things I like. ("Here are just a few of the things I like about Ruby") All: Like I wrote, all in all I want to leave it like it is, but if you find major errata/bugs/issues, please post corrections/fixes. I'm sorry, but the article is too short to include additional examples or text :( Tobi -- Tobias Reif http://www.pinkjuice.com/myDigitalProfile.xhtml go_to('www.ruby-lang.org').get(ruby).play.create.have_fun http://www.pinkjuice.com/ruby/
