+You might want to look back at the exercise errorsn (or its hints) to remind
+yourself about how `Box<dyn Error>` works.
+
+If you're trying to return a string as an error, note that neither `str`
+nor `String` implements `error::Error`. However, there is an implementation
+of `From<&str>` for `Box<dyn Error>`. This means you can use `.into()` or
+the `?` operator to convert your string into the correct error type.
+
+If you're having trouble with using the `?` operator to convert an error string,
+recall that `?` works to convert `Err(something)` into the appropriate error
+type for returning from the function."""
