...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);
    }
}
