Not with autocompletion, no.  HighLine doesn't allow you to manually  
set the autocompletion Proc used by Readline.  Perhaps we should, but  
then if you do that you probably aren't gaining anything from HighLine  
and you should probably just use Readline manually.

Sure, just set an Array of Strings with the number and description as  
you show above for the values.  They will auto complete fine, and you  
can strip the description after you have their answer.
