Returns whether <code>match</code> is a real match rather than <code>null</code> — the readable way to test the result of <a href="regex-find"><code>Regex.find</code></a> / <a href="regex-exec"><code>Regex.exec</code></a> / <a href="regex-next"><code>Regex.next</code></a>, and the loop condition for a find-all.

Parameters:
- `match` — a `Match` value (possibly null)

    if not Regex.ok(Regex.find("abc", "\\d")) { print(1) }
  }
