    Suppress some more warnings from Clang.
    
    It likes to think lambdas a la:
    
        foo $ \u -> ...
    
    represent a kind of unicode extended literal.
    
    It also gets confused when you have things like:
    
        ... thing ... {- comment ... (???) -}
    
    where the (???) is mistaken as a trigraph.
