Maybe not, something simpler than a full ORM should be compelling 
also.

I guess you know about the ORM Vietnam [1], but also this [2] can 
be of some help in selling a simple D solution.

I would like to see, someday, something in D that:

  - can check at compile time the syntax of SQL;
  - can check at compile time the SQL query statement against the 
current DB schema;
  - can read the output of a DB schema dump at CT, and parse it 
into what is needed for the previous points (more complicated);

The first point should be easy today, the second and the last one 
involve more work...
