  latlon_infer(c('a', 'LONG', 'Longitude', 'lat')) # only the best alias is converted/used
  latlon_infer(c('a', 'LONGITUDE', 'Long', 'Lat')) # only the best alias is converted/used
  latlon_infer(c('a', 'longing', 'Lat', 'lat', 'LAT')) # case variants of preferred are 
      # left alone only if lowercase one is found
  latlon_infer(c('LONG', 'long', 'lat')) # case variants of a single alias are 
      # converted to preferred word (if pref not found), creating dupes!  warn!
  latlon_infer(c('LONG', 'LONG')) # dupes of an alias are renamed and still are dupes! warn!
  latlon_infer(c('lat', 'lat', 'Lon')) # dupes left as dupes but warn!
