Max, this is a great example!
However, as you noticed it's a bit long and in fact in its 
current state it wouldn't look good:

If there's no chance to make it shorter, my suggestion 
considering that there are two other ideas in the queue with a 
similar length problem:

https://github.com/dlang/dlang.org/pull/1759
https://github.com/dlang/dlang.org/pull/1762

would be to find a new home for such "one-page" D example. We 
plan to restructure the DTour (tour.dlang.org) anyways, so how 
about adding a new section like "D in action" to it?
