Clojure Abstraction Levels

If you have loop/recur consider looking at the whole sequence api

• If you want to apply a transformation to each element reach for map/mapv
• If you’re looking to remove items, look at things like distinct, set, filter, remove, keep…
• If you want to apply a side effect for each element reach for run! / doseq / doall…
• If you want to produce a single compound value from many look for specialised functions first, then at reduce
• If you want to produce a sequence of values that depend on the previous value look at iterate…
• If you need to manipulate something stateful into being a sequence-like thing look at lazy-seq or a transducers.

There are many many more — for example: using transducers

No file, test, or entry point is named in the issue. Start by locating the repository’s existing Clojure sequence API documentation, then determine where this abstraction-level guidance belongs and confirm the intended scope with maintainers. Done should be an agreed documentation change covering the relevant guidance without expanding beyond the chosen scope.
