What about gc_ptr<T*>?  IOW, what if the pointer is actually a pointer
to a c array of T or a std::vector<T> or a pointer to std::list<T>.

OOPS.  Just read the cppgc.txt which says:

4) manage arrays of objects

However, I'm still wondering if it cppgc can handle 
gc_ptr<std::vector<T> > or pointer to any other std container.
Do you have tests for these cases?
