A noob naming question, that I guess doesn't really have an answer, but I thought I'd try anyways. Consider:

(s/def ::triple (s/cat :e string? :a string? :v string?))

Now I may call this vec a triple:

["e", "a", "v"]

But what should I call the (s/conform ::triple) version of it?

{:e "e", :a "a", :v "v"}

I am thinking parsed-triple or conformed-triple, but I wonder if there's a current idiom. If I have some functions that work on one type vs another, I worry about wonky names.

named tuple may be confusing as far as element order is not garanteed

Kirill Chernyshov 2023-02-22T09:15:15.909589Z

Why should order matter after conforming with the spec?

If you're already using tripple as a name, then name it tagged or named tripple as well instead of tuple IMO

dgb23 2023-02-22T09:19:30.819139Z

tripple is more precise than tuple

serioga 2023-02-22T09:20:43.012329Z

The word tuple means “finite ordered list”. https://en.wikipedia.org/wiki/Tuple It can be vague that named predicate drops the “ordered” characteristic. :-)

From the same article: > Many programming languages offer an alternative to tuples, known as https://en.wikipedia.org/wiki/Record_(computer_science), featuring unordered elements accessed by label.

btw python's named tuples are ordered and support access by index.

record tripple or just record seem to be good names 🙂

Kirill Chernyshov 2023-02-22T09:25:30.970999Z

It is even matching with clojure.core/record 🙂

Kirill Chernyshov 2023-02-21T17:33:15.207209Z

named-triple

Kirill Chernyshov 2023-02-21T17:33:32.154919Z

or just record

https://clojure.org/guides/spec#_collections mentions Conforms to map with named keys based on the cat tags . I would add more naming options like tagged-triple or named-triple . Python has named tuple which looks similar

Oo nice idea! Thanks team
