This wouldn't work, you'd have to rewrite it as:

    withSomeResource foo .
      withSomeOtherThing bar .
        yetAnotherBlockStructured thing $ ...

But it seems like your second example is more likely to come up for 'with' 
type blocks:

That should work, because '\x ->' extends to the end of the expression. 
Similarly:

    iWantMonadicValues $ do foo
                            bar
                            iAlsoWantMonadicStuff $ do ...

still works.
