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
Yes, you are absolutely right. By the way, this is not "the" tutorial, it is just one particular tutorial (and a very old one at that). Yes, I know its URL is haskell.org/tutorial, that is a historical accident rather than a blessing of canonicity. I am not sure who has access to the website to be able to fix it. -Brent
