But there's another API method for returning a single quote: (http://download.finance.yahoo.com/d/quotes.csv?s=RBS.L&f=l1) This wouldn't require any chunking expression at all. (get url "http://download.finance.yahoo.com/d/quotes.csv?s=RBS.L&f=l1";) But it also wouldn't require much of the code in the other languages. My point was that the one liner used in the example didn't represent a real world task, and therefore is in danger of being ridiculed. If we are to propose comparisons, it shouldn't be along the lines of this: How would you do the following in Java/C/etc? get last item of line 2 of url "http://ichart.finance.yahoo.com/table.csv?s=RBS.L"; but rather, How would you get and display the latest stock price for RBS.L from the internet in Rev/ Java/C/etc?
