>why have named return values (in learnMemory) if you return something different?

Probably to avoid declaring the function as `func learnMemory() (int, int)`.

No, you have to do that explicitly. You can do `return`, though, which will return the variables whose names match the definition.

To describe what you are returning. An int tells you a lot less than status404s int.

Because the variable are already declared and ready to be used. Difference can be seen here → http://play.golang.org/p/IVPiw_2Uph
