Boring in D. :p

template maxSizeOf(T...) {
   enum maxSizeOf = compute();

   auto compute() {
     size_t result;
     static foreach (t; T) {
       if (t.sizeof > result) {
         result = t.sizeof;
       }
     }
     return result;
   }
}

void main() {
   pragma(msg, maxSizeOf!(double, char, string));
}
