It seems strange and not useful that ValueObject is the base class of objects
that *can't* be passed by value.

Objects deriving from ValueObject *can* be passed by value, but we want them to
declare their own copy constructor and assignment operator to make it clear.
As you can see by the number of patches (you are actually commenting on an older
patch :-) there was a lot of discussions here on what is the best style. The
compiler on the Mac is also buggy and difficult to please. We may revisit this
at some time.
