Yes, but a litigious ActionScript scripter using Adobe's Flex might argue you can also do the above task with a single line of code, indeed a shorter one. (myHttpService.send() ) So long as the contest rules don't include XML descriptions of objects in the definition of code. (In Flex, you can use XML to define a programs's layout, and also bind text fields to the results of http calls, so no listener is necessary.) But it doesn't mean it's any easier to do in Flex overall. Just the opposite, I'm sure. I just don't think that pure code comparisons provide accurate comparisons of what's involved. And can perhaps deflect attention from the benefits of using Rev. With the stock quote example, I can open Rev, write my script and see the result without saving a single file. I'd even be willing to write a few more lines of code in Rev if it was required rather than sacrifice the overall simplicity of completing the task in hand.
