Following a discussion from a few days ago, I've added two new macros
to clojure.contrib.duck-streams:
(defmacro with-out-writer
"Opens a writer on f, binds it to *out*, and evalutes body."
[f & body]
`(with-open [stream# (writer ~f)]
(binding [*out* stream#]
~...@body)))
(defmacro with-in-reader
"Opens a PushbackReader on f, binds it to *in*, and evaluates body."
[f & body]
`(with-open [stream# (PushbackReader. (reader ~f))]
(binding [*in* stream#]
~...@body)))
