Thanks for the feedback, it is in.

I would need to dig up notes.

I think one reason is that, as illustrated by the breakpoint, things are 
not as correctly laid out as you might expect.

The colums within a row are tuples since, for a given table, the number 
of colums and their names should be known and each column could have a 
type different to the next.  Hmm, and tuple fields get names :-)

BTW, I missed the varobj stuff when reviewing all the output.
