Examples:

go
seq := func(yield func(int) bool) {
    _ = yield(1)
    _ = yield(2)
    _ = yield(3)
    _ = yield(4)
}
hasPrefix := it.HasPrefix(seq, 1, 2)
// hasPrefix == true
go
seq := func(yield func(string) bool) {
    _ = yield("hello")
    _ = yield("world")
}
hasPrefix := it.HasPrefix(seq, "hello")
// hasPrefix == true
go
seq := func(yield func(int) bool) {
    _ = yield(1)
    _ = yield(2)
    _ = yield(3)
}
hasPrefix := it.HasPrefix(seq, 2, 3)
// hasPrefix == false
