I don't think so... but if that gets me where I need to go, I'm all ears. :-)

I doubt inheritance will do the trick here. Spam isn't a base class, it
defines a container object.
I have several instances of spam, each of which contains (let's say) many
thousands of instances of eggs. I want for changes made to a single
instance of eggs to be made known to the specific instance of spam that
contains it. Similarly, I want for any instance of eggs to be able to get
the value of any attribute of its containing spam object.
To put this more generally, I want a subobject to find its containing
object so that methods of the containing object can be called and
attributes of the containing object can be set/checked. I gather there's no
easy, pre-defined way to do this, so any namespace voodoo that can do the
trick would be most welcome.
