deleteDups()

[HyperChris at aol.com]

I used to use an Xcmd set called HyperExternals Pro and one of its useful 
XFCN's was deleteDups(). The main thing it did was to quickly eliminate the 
duplicate lines in a sorted list. Here is my transcript replacement ...
 function deleteDups pList
  repeat with x=number of lines in pList down to 2
     if line x of pList is line (x-1) of pList then delete line x of pList
   end repeat
  return pList
 end deleteDups
 ... but I thought it might be fun to see what others have to offer up that 
would be more elegant and clever! Anyone?
