Then this programming paradigm cannot interact with one another. If I have subroutine that does X and another that does Y. How do I compose them? Composability is basically saying, "You can then do Z using X and Y" which is already explaining how its done. So you end up with a language where no subroutine can reference another, because that would constitute how.

No, it is complementary. For example, the quicksort algorithm/function you are indirectly using is available in just at another level of abstraction. Clearly we are far from writing algorithms using a "what" approach. It can even be impossible but I wrote about this concept because we have a codebase of algorithms and higher level frameworks that enable us to focus on the "what". I can never imagine a working paradigm like this decades ago.
