Building off of something Benoit mentioned about conj not being about order, but about adding to a collection, consider conj’s behavior when adding a map-entry to a hash-map:  (conj (hash-map :a 4 :c 1) [:b 3]) => {:c 1, :b 3, :a 4} conj is an interface for adding– not to be conflated with orde

Re: OK idea to replace conj and cons with "prepend" and "append" macros that have consistent behavior and return same types as args?

Another way to think about it is lists and vectors are different and the idiomatic way to add items to them is different. A (singly-linked) list is usually prepended to (otherwise you have to walk the entire list to find the end). A vector is usually added to at it’s n+1 index, where n is the si
