Not sure if this came up already, but there is a less general version of
void in Foreign.Marshal.Error:

void :: IO a -> IO ()
    Discard the return value of an IO action
Are there plans to unify the two? Perhaps Foreign.Marshal.Error can just
re-export void from Control.Monad?

Don brought it up, and it's a consideration behind picking the name 'void'.

Re-exporting with the type signature (ie. rewrite it to be void :: IO
a -> IO (); void = Control.Monad.void) is easy and won't break
anything; it's something that can be done after Control.Monad.void has
been added. One thing at a time.
