How about (setf (symbol-value (gentemp)) (make-piece))? This gets the
effect you want. However, you don't have a handle on the name after
this, so you probably want something like:

(let ((sym (gentemp)))
  (setf (symbol-value sym) (make-piece))
  ...)
which gives SYM a value which is the name of your piece. Symbol-value can 
access it then.

Hope this helps.
