I just saw this on the JavaWorld article (great article by the way:
http://www.javaworld.com/javaworld/jw-05-2009/jw-05-clojure.html
) <http://www.javaworld.com/javaworld/jw-05-2009/jw-05-clojure.html>
(defmacro with-open [bindings & body]
`(let bindings
(try
@body
(finally
(.close (first bindings))))))
...really? Is there some reason it only closes the first of the
bindings vector? It's not at all uncommon (though i wouldn't call it
common either) in C# to do:
using ((IMyFoo foo = GetMyDisposableFoo())
(IMyBar bar = GetMyDisposableBar())){
...blah blah blah
}
It seems like this idiom would be easy to implement in this macro. Or
am I missing something?
