+But note that when using a scalar reference the column in the database
+will be updated but when you read the value from the object with e.g.
+
+ ->somecolumn()
+
+you still get back the scalar reference to the string, B<not> the new
+value in the database. To get that you must refresh the row from storage
+using C<discard_changes()>. Or chain your function calls like this:
+
+ ->update->discard_changes
+
+ to update the database and refresh the object in one step.
