Did the compiler not tell you what the alternatives were that it was
forced to choose from? That would help me to understand where the
ambiguity is. As far as I can see, there's only one conversion path:
there's a template operator Null<T, B> in coldata.h which should be able
to convert ColData objects to Null-wrapped ColData objects.
One sticky point I see is that there is no operator== for the Null
template. Maybe the compiler wants to see one?
