...alternatively, you could create a wrapper struct for the 
pointer, do 'alias this' on said pointer, and then overload 
opIndex to call static assert(0);.  Like this:


struct Ptr(T) {
     private T *_ptr;
     alias _ptr this;

     this(T *val) {
         _ptr = val;
     }

     void opIndex(size_t index)() {
         static assert(0);
     }
}
