Returns all distinct elements from given collections (union of all collections).

Examples:

go
seq1 := func(yield func(int) bool) {
    _ = yield(1)
    _ = yield(2)
    _ = yield(3)
}
seq2 := func(yield func(int) bool) {
    _ = yield(2)
    _ = yield(3)
    _ = yield(4)
}
seq3 := func(yield func(int) bool) {
    _ = yield(3)
    _ = yield(5)
}
union := it.Union(seq1, seq2, seq3)
var result []int
for v := range union {
    result = append(result, v)
}
// result contains 1, 2, 3, 4, 5 (all distinct elements)
