There are loads of different rules you can apply here...

- Are you writing a member operator? Return *this by reference

- Are you writing a non-member operator? Return by value and either do your damnedest to trigger NRVO/RVO or write a move constructor in C++11

- Are you transferring ownership of something? Return a std::unique_ptr

- Do you want to read something that legitimately might or might not exist? Use a const pointer using 0 as an error value

- Do you want to read something that should exist and if it doesn't then the whole program's sunk? Return a const reference and throw if something goes wrong

- Are you returning a writable address or a reference to one or more of an object's data members? You are insane, please report to the funny farm

- Do you want to return a reference to an object to an automatic variable? See previous answer for details.

One thing to remember though is that sometimes you'll want to do something that's a bit unusual and you'll have to do something unusual to implement it.

Cheers,

Ash
