## While, For, and Loop 实操
Move offers three constructs for looping: `while`, `for`, and `loop`.
```rust
module 0x42::Demo3 {
use std::debug;
#[test]
fun test_if() {
let x = 5;
let x2 = 10;
if (x == 5) {
debug:...
...:xcoin::X;
public fun publish() {
// Illegal, X can not be constructed here.
coin::publish_coin(X {});
}
}
```
那么如果此时有一个hacker想要抢先注册这个token，那么需要构造模块中的x提前调用`publish_coin`函数，但是由于Move中的...
