What is the Go equivalent of C++ initializer lists?

Question

In C++, I might do the following:

for (const string& key : {"foo", "bar", "baz"}) {
  DoSomeThingWithKey(key);
}

The {"foo", "bar", "baz"} is a std:initializer_list. Awesomeness.

Is there an equivalent idiomatic pattern for Go?

Answer 1

Simply use a slice:

for _, value := range []string{"foo", "bar", "baz"} {
    fmt.Println(value)
}

or alternatively an array:

for _, value := range [...]string{"foo", "bar", "baz"} {
    fmt.Println(value)
}
