Model Driven Development

[Bruce Adams]

Hi,
    I don't know if this has come up before but is always worth a review  
every so often. As far as model driven development goes
are there any tools out there currently that support or plan to support  
code generation for D and round trip engineering
(that is syncing the code back into the model). I'm also curious as to  
peoples opinions on model driven development in general
(please keep the religious flame wars to a minimum though eh :).

Regards,

Bruce.
