Yes, it is in D. Nothing is released yet. It needs to be polished a little so that there are no known embarrassing shortcomings anymore. (eg. the parser cannot parse extern(...) declarations in alias declarations yet, and I need to finish making a minor tweak to how template instances are analyzed in order to get circular dependency detection to work reliably.
How are you implementing the code generating back-end for the compiler?
In your design, I would recommend keeping the front-end separate from the back-end so that maybe the front-end can be connected to the LDC or GDC back-ends.
