Taking things off the reader and then pushing them back on seems a

little odd to me--isn't there a way to just "peek" at the next character

PushbackReader exists because pushing back one or a small number of characters can make parsing text significantly easier. Rather than forcing every input stream to allow some pushing back (or peeking), PushbackReader encapsulates that capability and works with other streams to provide it. I see that issue 79 against Clojure requesting this change is still open. If auto-wrapping of readers is no longer a change you'd like to see, would you please either withdraw it (if you as the originator have that capability) or add a comment to it requesting that it be withdrawn?
