Since pipes and parentheses are substitutes, it seems like teams have to agree on one or the other to avoid having different ways of doing the same thing. And, I think parentheses usually win because everyone is familiar with them, while only a smaller and more hardcore group is addicted to the pizza operators.
So, I have wondered, what would that look like if a team went 100% pizza. And “No parentheses” was their style. What if Elm removed parentheses? Could it work?
