This would be due to the fact that even the "trivial_archive"
inherits functionality from common_?archive.  The archive
concept doesn't require this - but most archives will want to
do this - then override the implementation of common_?archive.

truth is I don't remember all of this stuff.  But it would seem
that the serialization of pointers is a lower level.  This makes
sense since there is more than one idea about how to save/restore
a pointer.  The current implementation creates a new object
when a pointer is de-serialized.  But it didn't have to be this way.
Someone else might want to define it as to just restore the
value pointed to.  Someone else might want to prohibit it. et.

If it were me, I would leave them undeclared.

and I would have chose a different name that reflects
the more specialized nature of this implementation. Also
binary_object is used in the library to mean something
specifice.  Also the archives in the the library are templated
on stream type binary/text - so binary isn't such
a great name either. maybe something like

(binary | text) _static_(i/o)archive

static sort of suggests that there is no dynamic memory
allocation.
