Can I just leave it hanging and rely on the garbage collector to close
it in the fullness of time?

Because of laziness, I believe there's no point in my writing the
following:

 >    load fn = do handle <- IO.openFile fn IO.ReadMode
 >                 contents <- IO.hGetContents handle
 >                 let xml = XP.xmlParse fn contents
 >                 IO.hClose handle
 >                 return xml

Is that correct?
