Hi Joby,

I think this causes other problems - I tried it myself earlier and although 
I didn't see the error, the data I got back wasn't what I wanted.

When you do Object->Attributes->Named('ddd') then the Attributes object is 
cached in the Object (see Record.pm). By limiting the Attributes object to 
just the ones that match the name (below), the cached object's attributes 
are now limited and subsequent calls to Object->Attributes will get you 
just those with the name you used before, not all the attributes.
