   I am probably missing something. The below does not compile:
   
   ```rust
   let array: StringArray = [Some("foo"), None, Some("bar")]
           .iter()
           .collect();
   ```
   
   isn't it enough to use `.map(|x| x.as_ref())`:
   
   ```rust
   let array: StringArray = [Some("foo"), None, Some("bar")]
           .iter()
           .map(|x| x.as_ref())
           .collect();
   ```
   
   it is 20 more characters, but it does not seem _that_ bad?
