This would be beautiful!  I can picture myself having fun 
writing code like this:

conn.Exec ("select .....");

copy (conn.tuples().begin(), conn.tuples().end(),      ostream_iterator<tuple> (cout, "\n"));

(or even conn.begin(), conn.end())

or:

void custom_print_row (const tuple & row)
{   cout << "ID: " << row["ID"] << endl        << "Name: " << row["name"] << endl         << "Age: " << current_year()
-row["year_born"]         << endl << endl;
 
}

for_each (conn.begin(), conn.end(), custom_print_row);

Things like that...  Definitely nice!
