I think a better model to follow would be SQL alchemy which allows you to test the tables

You mean that the columns of a table should be declared as attributes of
the corresponding class? Hmm, I don't know, I like that Rails way.

They are using pragmas to accomplish this. I guess an equally good
implementation in D would use custom attributes for this once (if) they
are supported.

I'm pretty sure you can create an ORM library like that with what we
already have in D today. If needed, mixins can be used like custom
attributes, but it will look very ugly.
I can also add that I think D can do a lot better job than C++ with this ODB
library. I think it would be possible to do this:
class Person : Model {}
And let the super class get all info from the database, just like ActiveRecord
in Ruby on Rails.
