Two-way-streams and gray streams
ABCL runs into troubles with the following example:
shell> cat test.lisp
(in-package cl-user)
(require 'gray-streams)
(defclass out (gray-streams:fundamental-character-output-stream)
((buffer :initform (make-array 200 :element-type 'character
:adjustable t :fill-pointer 0)
:reader out-buffer)))
(defmethod gray-streams:stream-write-char ((s out) (c character))
(vector-push-extend c (out-buffer s)))
(let ((out (make-instance 'out)))
(write-string "foo" (make-two-way-stream *standard-input* out))
(assert (equal "foo" (out-buffer out))))
