Just how much of a sub-object to dump is always a tricky call. Often the
right call is at a pointer or reference boundary.

Note also that if you implement the children function of the gdb api for
the top-level type, you will get any sub-pretty printers that exist for
free. And if they don't exist, gdb will use its default printing mechanism,
which is often good enough.
