I'm not sure I like this being solely a global decision - it makes custom
allocators much harder, and it makes it hard for allocators that have different
policies, e.g
```cpp
struct ImportantStruct {
void *operator new(size_t) { /*tagged allocator*/ }
};
struct BoringStruct {
...
};
struct SomeOtherStruct {
ImportantStruct *important; // should be tagged pointer
BoringString *lessImportant; // should be a non tagged pointer
};
```
This would again require a struct attribute to indicate the pointer policy
