This looks more like two -> combinators with a token in between. I think it looks kind of nice in simple cases but the two arrow and extra spaces add 6 additional characters to each combinator name, which gets old once you nest; and once you start nesting you could get something like:
article -> shadow -> heading -> descendants -> p…
Where it’s getting a bit harder to spot the combinator names from the element names vs.
article ^shadow heading ^descendants p
…which is admittedly more compact and effectively disambiguates combinators from the things they apply to fairly well.
