Thanks to Andrei Alexandrescu for this great presentation! Although I'm judging by the video alone, I feel you captivated the crowd quite well with this one :)

Some comments:

Using goto for cleanup is a common trick probably known to most modern C users. Maybe the C slide should have used goto, or there could have been two C slides; the current setup was perhaps slightly unfair to C programmers who would never think of writing several indentations of rollback-cleanup.

C# programmers might want a word with you about slide #8, as C# does have the `using` statement to help with cleanup in a sort-of RAII-style way, except it still needs a level of indentation; it's not revolutionary and not nearly as good as D style or even C++ style cleanup, but it does improve it over the pure Java model.

The editor comment would've made a great segue into mentioning VisualD - I don't actually know much about the composition of the audience, but it is a Microsoft hosted conference :V

I think it's important to emphasize that string mixins are only available at compile-time, I think the host of eval()-like functions in other languages have soured quite a few people to the idea of mixing in strings as code. It should've been obvious to anyone who was paying attention, but it's probably worth mentioning nevertheless.

Slide #23: font size too big 8)

Anyway, overall, one of the best presentations about D I've seen yet, it's always a joy to watch these videos.

Agh, I missed it, sorry! I deleted mine.

(Hey, mine linked directly to the HTML5 version, I take solace in this fact :P)

The generalized palindrome doesn't work with odd lengths.
simple fix:

bool palindrome(Range)(Range range) {
    for (; !range.empty; range.popFront(), range.empty || range.popBack()) {
        if (range.front != range.back)
            return false;
    }
    return true;
}

Call me stupid, but how exactly is the version from Andrei's slides broken?

Disregard that, I was looking at the array slicing version.
