Order of instantiation is irrelevant outside of RAII management patterns, since an object may outlive its creator (that's the point).
If block A was instantiated first then block A is necessarily the parent of block B.
What do you mean by the block_ptr will be invalidated? The pointer will be set to zero?
Precisely.
So that's something any user should be ready for, check block pointers are non-zero in destructors?
It's already done implicitly in the destruction of the block_ptrs. Right before they'll be destroyed the pointer will still refer to the deallocated memory block.
Right, but the user could still try do do some_block_ptr->some_member_function() if some_block_ptr is null, this will lead to an error. You should talk about this in the documentation.
