Try adding it and see what happens. This will likely change in a future Rust edition. 30.6 實作不安全的特徵 與函式類似，如果實作程序必須保證符合特定條件才能避免未定義的行為，您可以將特徵標示為 unsafe。 舉例來說，zerocopy crate

But there's an exception: future calls to newfun from the REPL work as expected, being able to both see and call the new definition of newfun. However, future calls to tryeval will continue to end return g g() = 0 end as it is not clear what function will end up getting defined. In the future, it might be an error to define local methods in this manner. For cases like this use anonymous
