I am having the case in which a function with the following code:

func halfMatch(text1, text2 string) []string {
    ...
    if (condition) {
         return nil // That's the final code path)
    }
    ...
}

is returning []string(nil) instead of nil. At first, I thought that perhaps returning nil in a function with a particular return type would just return an instance of a zero-value for that type. But then I tried a simple test and that is not the case.

Does anybody know why would nil return an empty string slice?
