省略号的所有用途

I am learning Go and it seems the ellipsis ... has at least 3 uses:

// #1: Array declarations
a := [...]int{1, 2, 3}

// #2: Variadic parameters
b := func (ints ...int) []int { return ints }(1, 2, 3)

// #3: Slice spread
c := append([]int{}, []int{1, 2, 3}...)

Does the ellipsis have other uses than the above 3?

As noted in the comments, these are all 3 use cases in the language, although the go tool uses ... as a path wildcard.
