I have a suggestion about your region allocator: Use allocator
instances instead of global new/delete procedures.

I don't like to override the DEFAULT operator new/delete. This makes
your code doesn't work well together 3rdparty code (if it also
override them).

I suggest ISO C++ cancel this feature, just like we can't override
operator+ of all C types. That is:

1. You CAN NOT override these operators:

   void* operator new(size_t size);
   void operator delete(void* p);

2. You CAN override NON-DEFAULT operator new. Such as:

   void* operator new(size_t size, my_allocator& alloc);

3. There is no need to override operator delete. If you need delete
objects in special way, just use:

   alloc.destroy(obj);
