Are there more up-to-date D template tutorials?

A bit off topic/ranty but I did find the book by Ali on D 
extremely useful, but it was good as an 'introduction'. I feel 
like when it comes to more advanced features (such as templates, 
mixins, ranges, concurrency, etc) there are no resources out 
there, but I guess that's the 'cost' of picking a lesser-known 
language. Hopefully in the future there will be more books 
written on this language, if there was a book on the advanced 
features of D I'd happily purchase it :)
