I must  be misunderstanding:

   #!/usr/bin/zsh

   function tt ()
   {
   integer -x unique_to_tt=2
   }

   8 /aWorking/Zsh/Source/Wk 1 $ echo $unique_to_tt


   8 /aWorking/Zsh/Source/Wk 1 $ . temp1; tt; echo $unique_to_tt
   2

... so it's visible externally as you say, but it's not going away either.
