just translates to either a list with one or more elements or an empty list?
Clojure actually provides a rich set of persistent data structures in addition to lists like sets and maps. I think he's referring most commonly to map keys here, but the concept applies to lists as well.
fail as well as succeed
Great point. You're absolutely right, Maybe is being shoehorned here into something it isn't, but happens to be applicable towards.
it's a way of representing sequential computations
This is definitely more concise than my current word salad answer. I still have never managed to "English" the idea as succinctly as I think it should be able to be expressed but I remember specifically they day it "clicked" - truly not a complicated idea.
I think his point is that this idea of the potential for failure or gaps in your data will inevitably (in certain systems) apply to all data, so then why are we dealing with it in the domain level at all? Clojure kinds offloads that to how it manages data in general with it's STM engine. However, moving the complexity doesn't avoid that complexity.
For further actions, you may consider blocking this person and/or reporting abuse
We're a place where coders share, stay up-to-date and grow their careers.
Thanks for the detailed response!
