これにより、可能であれば Vim9 script 構文を利用したスクリプトを書くことができ
ますが、Vim9 のないバージョンでも動作するようになります。

Note Vim9 の構文は Vim 9 より前に変更されたため、現在の構文 ("import" ではなく
"import from" など) を使用するスクリプトではエラーが発生する可能性があることに
注意してください。これを防ぐには、代わりに |v:version| >= 900 をチェックする方
が安全です。

これは、2通りの方法でしか機能しません:
1. "if" 文は false と評価され、`endif` までのコマンドはスキップされ、
`vim9script` が実際に実行される最初のコマンドとなる。

This allows for writing a script that takes advantage of the Vim9 script
syntax if possible, but will also work on a Vim version without it.

Note that Vim9 syntax changed before Vim 9 so that scripts using the current
syntax (such as "import from" instead of "import") might throw errors.
To prevent these, a safer check could be for |v:version| >= 900 instead.

This can only work in two ways:
1. The "if" statement evaluates to false, the commands up to `endif` are
skipped and `vim9script` is then the first command actually executed.
