No need to duck, well not from me at least. I just forgot the smiley
(didn't think it was needed...) . NULLs are indeed a travesty of the
relational model.
I came across this oldish article on the subject recently.

I've not read it in detail, but it sounds like a possible compromise to
the (unproven) problem of relvar proliferation in a fully normailsed
database.
