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.


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.



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.
