 In Rust, it can sometimes be a pain to pass regular expressions around if
-they're used from inside a helper function. Instead, we recommend using the
-[`once_cell`](https://crates.io/crates/once_cell) crate to ensure that

 ```rust

 fn some_helper_function(haystack: &str) -> bool {

     RE.is_match(haystack)
