Lately I had to write some sqlite3 code in D. And I really hated writing it. So I wrote me some CTFE generator for it. It uses all the fun UDA, CTFE string mixin template magic, we all love. The generated code is as fast as the hand written one. I wrote some of it down. http://rburners.tumblr.com/ The article also holds a link to the source/benchmark. Maybe this is to some interest to other people as well.
