Which type to assign to  ? Right now I'm using
instance HL.LogHandler () where -- doh! find a better way to pass an empty list below
setLevel = error "should never be rearched"
getLevel = error "should never be rearched"
emit = error "should never be rearched"
close = error "should never be rearched"
HL.updateGlobalLogger "" (HL.addHandler fh . HL.setHandlers ( :: [()]) )
But I'm not satisfied with that. But I couldn't find a better solution
either. Eg I've tried
 :: [SyslogHandler] (SyslogHandler is not exported, is it?)
 :: [GenericHandler ()] (GenericHandler isn't exported either?)
