Black: formatting of fluent method calls

Question

I'm using the black formatter, and I'm having trouble getting it to respect my wishes for fluent method chains like this:

            result = (
                data
                .some_method()
                .some_other_method(arg1, arg2)
                .yet_another_method_with_longer_name(arg3)
            )

, which gets reformatted by black as

            result = data.some_method().some_other_method(arg1, arg2).yet_another_method_with_longer_name(arg3)

.

The docs (at https://black.readthedocs.io/en/stable/the_black_code_style/current_style.html#call-chains) are pretty terse on the subject, saying

Black formats those by treating dots that follow a call or an indexing operation like a very low priority delimiter. It’s easier to show the behavior than to explain it.

It may be easier for the writer, but not for the reader - I don't get it. =)

I'm looking for something like the "magic trailing comma" to tell the formatter that I desire one method call per line, so please format it that way. But of course, an actual comma is not valid in this situation, it would turn the right-hand-side into a tuple.

I tend to think of #fmt: on/off as a very last resort, so I would prefer to avoid using them if at all possible. Because of the libraries I'm using (and writing), there would be a lot of them in the code.
