Yeah, but scattered all over the different chapters. And not
describing those that are the same in C++ is like not describing
the types float and short, just because they are the same in C++.
I find it lacking if I have to tell a newbie "look in the
documentation for some other language for the definition of the
operators that you can't find here somewhere"
