This post seems to be written by a highly intelligent person, but I fear it comes off as reactionary. They're picking on an example from the slideshow that was posted a few days ago, I believe, and then saying, "This is stupid!" I would rather have someone take a feature from a very new language, and rather than be reactionary, post about how they felt when they first heard of this feature, ("Weird!", "Wild!" "UH-OH", and then go, "Well, hey, let's see what's it's good for", and try to use the feature. Then, and only then, it would be interesting to read their response of the feature: "I first thought this, but in actuality it saved me a lot of time/came in handy/saved me a ton of lines of code, and hey, it didn't affect anyone else's code!" Or, even, "Yup, just what I expected - yadda yadda - and HERE'S HOW I'D IMPROVE THIS FEATURE SO IT'S MORE OF THE AWESOME" Then we have something to talk about. $0.02 and all. Saves a pissing match.
