Details:

to maintain write-read invariance.  Consider

1 ]=> (write '|#foo|)
#foo
;Unspecified return value

1 ]=> (with-output-to-string (lambda () (write '|#foo|)))

;Value 14: "#foo"

1 ]=> (with-input-from-string (with-output-to-string (lambda () (write
'|#foo|))) read)

;Ill-formed boolean: #foo
;To continue, call RESTART with an option number:
; (RESTART 1) => Return to read-eval-print level 1.

2 error> 

I would expect the last of these forms to return a symbol
that was eq? to the original '|#foo|; and I would expect the
first two to produce whatever output is appropriate to
ensure this.
