Actually they do prohibit those features that arguably cause more damage than benefit. c++ exceptions? in an unmanaged (runtime engine not managed by some sort of VM) language you can't really assume anything when an exception occurs, you can't assume that you will be able to allocate more memory from the heap, for instance - if the heap is corrupted then this will just not work. RTTI ? it costs a lot, well and you can do without it; Besides requirement of RTTI (assuming that the library does RTTI) will prevent you from using third party libraries that might be of use. Resolution: skip.
