specified type. The

- * - When `U` is a class, fields for the class will be mapped to columns of
the same name
- * (case sensitivity is determined by `spark.sql.caseSensitive`).
- * - When `U` is a tuple, the columns will be mapped by ordinal (i.e. the

Review comment:
Oh OK. Maybe I'm crazy but I thought `- foo` style lists work, but remember
that sometimes they don't unless there's a blank line above it. I'm just
wondering if that's the issue here. Or if it's not -- there are many more
instances like this in the code, no? let's fix more of them if it's necessary
