> SP_TYPE() macros should be reimplemented as dynamic_cast so that they generate compile-time errors when something not derived from SPObject is passed.

 

I checked that and it is currently impossible without changing a huge amount of code. Some parts use these GSLists and they store void-pointers. Thousands of SP_TYPE-lines would fail compilation. I'd suggest doing this change later.
