Is it possible to implement

in a non-recursive way?

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));
}
