namedreturns [flags] [files]

List of available flags now:

• a: disables check for anonymous functions.
• t: disables check for test files.

Flag a disables check for anonymous functions (callbacks):

func foo() {
    // callback is an anonymous function, flag -a disables check for such kind of declarations
    callback := func() (int, error) {
        ...
    }
    ...
}

Flag a disables check for function in test files. Test files are identified by test.go suffix.
