I also think it's a bit weird to flip direction of composition, but there are a couple of advantages -- 1. It keeps the "imperative" feel, so that you can write person.address.zipCode rather than zipCode.address.person 2. There's an argument that mathematical functions are "back to front" and that it would be more natural to write functions left to right, i.e. (x)f rather than f(x), so that the function composition f.g is "apply f then apply g" rather than "apply g then apply f" which is where we are at the moment.

Let's just go ahead and steal (<) and (>) for directional function composition everywhere. I'd rather just write `lt` and `gt`. x & f > g > h === h < g < f $ x

  We already have (<<<) and (>>>) so you're nearly there :)

    Those always feel comical to use to me. It's like having a 747 landing strip to help guide a duck in for a safe landing.

      Yes they are rather big :)

> There's an argument that mathematical functions are "back to front" and that it would be more natural to write functions left to right Totally agreed, but until programming languages adopt "x f = ..." for a definition of f then I'd prefer to stick to composing the traditional way round.
