I agree with you, indeed it is much too long for a carousel ;)

And it should be made even simpler.

But I still think that the first and only sample code someone 
should read when coming for the first time on the D website 
should be this kind of example, which shows how simple and 
straightforward the D code looks like.

It's very important to reassure the visitor curious about D on 
how easy it is to learn and use D, showing him that D's syntax is 
familiar, and the code is very readable and concise.

Some first-time visitors may be meta-programming experts, but 
many others (including me) are just looking for a simpler 
alternative to existing languages, which allows them to quickly 
program their stuff in an easy and efficient way.

And for those looking for a language which allows to program 
complicated things in a simpler way, as D indeed allows to do it, 
this should also be shown. But I don't think that this should be 
the first example someone sees.

That said, I'm not totally against code carousel.

The one on the Python website is very well done.

Its code snippets are very simple on purpose.

Python's landing webpage is very encouraging, and shows that this 
scripting language can be picked up quickly.
