This:

     with open(foo), open(bar):
         .write(baz)  # does what?

is basically just a shorter way to write this:

     with open(foo):
         with open(bar):
             .write(baz)  # does what?

so that suggests that it would pick the last one.

Anyway, the exception (or warning?) could be raised at compile-time if 
the leading-dot form was used in a 'with' that had more than one expression.
