I guess the biggest hurdle there is integrating D concepts info into

Rainer bundles Mago with VisualD. I wonder what that's doing lately...

Aldo has put a lot of work in extending mago to 64-bit. I guess the next version of Visual D will come with it.

Mago had D expression evaluation from the start, showing associative array elements was added a bit later.
