Oh, now I see what you mean.  You're adding an array with typeset -T
so that -U will remove duplicates from the scalar, but then you want
only the scalar to be left at the end -- the array is just a vehicle
for the "uniqueness" semantics.

Is using a tied array really that much faster than VAR=${(us.:.)VAR} ?
