In addition to better static type control you can track pointers or a list
of pointers at compile-time and then use it at runtime to set up the schema
and to load an object with all its relations.

where members are grouped by classes (bases and
end class), types of form elements are determined automatically from member
information and pointers are represented as references. Most exciting is
that you get it using one function call! (if you described all classes
earlier).

from the {o,i}stream features which are only concerned with

Only pipestream is thread safe. Iostreams are not.
