[Haskell-beginners] typo in tutorial?

[Jason Sachs]

is there a typo in the tutorial? http://www.haskell.org/tutorial/io.html

sequence_        :: [IO ()] -> IO ()
sequence_ []     =  return ()
sequence_ (a:as) =  do a
                       sequence as

Shouldn't that last line be the following? (if so could someone please
report it? i don't know where to report typos/bugs in the tutorial)

sequence_ (a:as) =  do a
                       sequence_ as
