As you worked much with ast.dump(), what multi-line formatting do you prefer, the current

        Module(
            body=[
                If(
                    test=Name(id='x', ctx=Load()),
                    body=[
                        Expr(
                            value=Constant(value=Ellipsis))],
                    orelse=[
                        If(
                            test=Name(id='y', ctx=Load()),
                            body=[
                                Expr(
                                    value=Constant(value=Ellipsis))],
                            orelse=[
                                Expr(
                                    value=Constant(value=Ellipsis))])])],
            type_ignores=[])

or with closing brackets on separate lines?

        Module(
            body=[
                If(
                    test=Name(id='x', ctx=Load()),
                    body=[
                        Expr(
                            value=Constant(value=Ellipsis)
                        )
                    ],
                    orelse=[
                        If(
                            test=Name(id='y', ctx=Load()),
                            body=[
                                Expr(
                                    value=Constant(value=Ellipsis)
                                )
                            ],
                            orelse=[
                                Expr(
                                    value=Constant(value=Ellipsis)
                                )
                            ]
                        )
                    ]
                )
            ],
            type_ignores=[]
        )

The latter make contain long stairs of closing brackets.
