"opBinaryRight":

It's a "neat" feature that allows operators being member 
functions, yet still resolve to the right hand side if needed. 
For example:
auto result = 1 + complex(1, 1);

Will compile, and be re-written as:
auto result = complex(1, 1).opBinaryRight!"+"(1);

In contrast, C++ has to resort to non-member friend operators to 
make this work.
