I can't remember the exact context, but I once tried to solve a problem
by attaching a non-special text property to completion strings, which
would be used by the caller to map the completed string to another
object.  That can be done other ways, like making the completion strings
keys in an alist or an obarray; but since the completion list was
dynamically generated, it seemed cleaner to me to avoid creating the
additional data structure.
