Beat you to it: http://code.dlang.org/packages/d-pcg
It only has the basic generators at the moment. I'll look into
the more advanced stuff.
(Also 64 bit outputs aren't implemented yet because they need a
128 bit uint for state. I noticed D reserves the names cent and
ucent but hasn't implemented them)
