[fset-devel] Rereading reader bug for collections with non-NIL defaults.

[Samium Gromoff]

Scott,

Evaluation of this form fails with an error:

(with-standard-io-syntax
  (let ((*readtable* (copy-readtable *readtable*))
        (v (with-default (map) (set))))
    (fset::fset-setup-rereading-readtable *readtable*)
    (with-input-from-string (s (with-output-to-string (s)
                                 (write (list v) :stream s)))
      (read s))))

..whereas this succeeds:

(with-standard-io-syntax
  (let ((*readtable* (copy-readtable *readtable*))
        (v (map)))
    (fset::fset-setup-rereading-readtable *readtable*)
    (with-input-from-string (s (with-output-to-string (s)
                                 (write (list v) :stream s)))
      (read s))))

...which probably suggests that the reader hasn't been conditioned
to take care of the trailing "/foo" syntax.
