I like this, but I also think some of the benefits can be had independently by combining several complementary techniques (in C++). The allocation can be handled by custom allocators for each object type. You can do only this and you avoid the double de-reference of handles. If you are fine with double-dereferences and also want to implement extra checks and use less bits for the pointer you could overload `operator->()`, e.g. struct CompressedPointer { uint16_t obj_id; Object \*operator->() { return Object::get_by_id(obj_id); } };
