+
+Handle LOB types in Oracle. Under a certain size (4k?), you can get away
+with the driver assuming your input is the deprecated LONG type if you
+encode it as a hex string. That ain't gonna fly at larger values, where
+you'll discover you have to do what this does.
+
+This method had to be overridden because we need to set ora_field to the
+actual column, and that isn't passed to the call (provided by Storage) to
+bind_attribute_by_data_type.
+
+According to L<DBD::Oracle>, the ora_field isn't always necessary, but
+adding it doesn't hurt, and will save your bacon if you're modifying a
+table with more than one LOB column.
