The main problem with SDL is it's name. It's not an overly popular project - it doesn't even have an article in Wikipedia. That alone is not a problem - if we had something against non-mainstream project we wouldn't be using D - the problem with SDL's lack of popularity shares it's initials with "Simple DirectMedia Layer" - a super-popular project with binding for most languages. This makes it very hard to google for Dimple Declarative Languae - because most of the things you'll find are about Simple DirectMedia Layer.
If you google "D programming language SDL" you'll find it.
