DataMapper, Validation, Crud issues

I don't have one at the moment.

The only option, and advocated by CodeIgniter, is to provide MY_xxx versions of every core class that needs to be extended in the Datamapper distribution.

And leave the problem of sorting out what to do when you already have one (with potentionally the same methods, but with conflicting functionality) to the user...

For myself, the suggestion was very simple. I don't develop new applications in CodeIgniter anymore, I switched frameworks.
