http://visula.org/relational/implementation.html contains:

   The reason this has to be a macro is because it needs to work with
   names, not just types.  It was felt that the benefits of being able to
   write customer.name or customers.name instead of column<1>(customers)
   or col<1,1>() outweighs the inherent disadvantages of using a macro.

why not use an enumerator:

    column<name>(customers)

instead of a number:

    column<1>(customers)

?  Would this eliminate the macro need?  This idea of using enumerators
for easier reading was one motivation for the indexed_types library
