Naming the return values of a Go function

Unlike C, Go allows you to name the return values of a Go function. Additionally, when such a function has a return statement without any arguments, the function automatically returns the current value of each named return value. Note that such functions return their values in the order they were declared in the definition of the function.

Naming return values is a very handy Go feature that can save you from various types of bugs, so use it.

My personal advice is this: name the return values of your functions unless there is a very good reason not to do so.
