What is the maximum number of values that a function can return in the Go language?

In the Go language, a function can return any number of values, and there are no restrictions on the maximum number of return values specified in the language specification. In practice, the number of return values is usually small (2-3), for example, to return a result and an error, but technically, more can be returned.

Example of a function with multiple return values:

func getData() (int, string, bool) {
    return 42, "answer", true
}

Thus, the limit on the number of return values is set only by common sense and convenience, not by the language.
