The file:

   http://www.boost.org/doc/html/visit_each.html

has:

   visit_each mechanism allows a visitor to be applied to every
   subobject in a given object.

but there's no definition of subobject or object.  Is a subobject
any instance of a class, or only those derived from
signals::trackable?

The file also contains:

   other uses may surface if used universally (e.g., conservative
   garbage collection).

does the "conservative" qualifier mean the subobjects are located
conservatively (e.g. comaring each word in the containing object
with some flag value)?

TIA.
