At first glance, the new operator overloading syntax looks cumbersome by
comparison to C++.  Adding the following example to the D docs would make it
clear what the advantage of the new syntax is, as well as not requiring people
to reinvent it repeatedly:

2. Use one mixin expression:

T opBinary(string op)(T rhs) {
     return mixin("data "~op~" rhs.data");
}
