Comment (by simonpj):

 > I also realized that unarise uses absentError wrong: absentError expects
 an Addr# argument (for a string that represents the "absent" argument) but
 unarise just uses absentError without an argument. So there's also a type
 error.

 That is pretty terrible. I suggest making a separate ticket and fixing it
 asap.
