   > How do duplicate column names work? If you look it up by name, you get the last one? But each gets an index?
   
   Yes, each column gets an index and index-lookups always work.  In pyarrow a name lookup raises an error if there are duplicate columns.  In arrow-rs it appears it always picks the first one.
