The compiled-pattern form of <a href="regex-matches"><code>Regex.matches</code></a>: returns whether the pre-compiled <code>re</code> matches anywhere in <code>text</code>. No per-call parsing, so this is the one to call every frame.

Parameters:
- `text` — the string to search
- `re` — a compiled `Regex` from `Regex.compile`

```ludic
program Demo {
  entry {
    let re = Regex.compile("[a-z]+")
    if Regex.test("hello", re) { print(1) }
  }
}
```
