    I wanted to ask why it’s bad, what did you change?

    Btw. the example function get_default is badly chosen, because unwrap_or_default exists.

      The original example was doing the unwrap_within an iterator doing some string parsing, so there was a lot of unrelated boilerplate around the actual unwrapping that made it really unclear, as well as usual unwrap_or_else to produce a constant value

      Ehhh, I was more using get_default as a placeholder for some function, as opposed to representing Default::default for the inner type specifically. I think it should be alright since only people familiar with rust would know about the default trait anyway. I did consider adding an unwrap_or_default example, but thought it was getting a bit off topic at that point.

         .map(|n| n.parse().unwrap_or_else(|_| std::i64::MIN))
        

        *shudder*

        unwrap_or_else and passing a closure that ignores its argument is a definitive smell. Probably gets caught by clippy.
