It just crossed my mind, in our latest product version, we have protocols

Sure. Languages. This is a data format, not a language.
Data formats do not exist in a vacuum. They are parsed by languages.
Some may have a fine-grained distinction between lists, arrays/vectors
and sets and some may not.
Why should I not inflate a edn-list into a vector in my language?
Is this too Clojure specific ?
I wouldn't say so. By definition the definitions of list,
vector/array and set encompass the behavior in question. I think
people are getting too wrapped up by the textual representations where
the forms (1 2 3) [1 2 3] and #{1 2 3} look fairly similar. By nature
Java has arrays, lists, maps and sets, so does Ruby and Erlang.
If they were redundancies in these structures, can't see why these three still
maintain this distinction. It's probably a safe bet to say that we need to
convey these
nuances in edn somehow.
