I strongly disagree with this. It should be this:

try_stmt: 'try' ':' suite
            (
                except_clause ':' suite)+
                ['else' ':' suite] ['finally' ':' suite]
            |
                'finally' ':' suite
            )

There is no real complexity in this grammar, it's unambiguous, it's an
easy enough job for the code generator, and it catches a certain class
of mistakes (like mis-indenting some code).
