Bonne journée à tous !

Good morning!

Morning

lost half an hour of my life on this:

(defn foo [{:keys [bar :as lol]}] lol)

I'm sure clj-kondo would have caught it in one way or another.

yup ;)

I posted a question on http://ask.clojure.org about this, since I do think this is nonsensical and could/should be caught by a destructuring-spec.

morning!

@slipset It's not nonsensical. you can use keywords in destructuring (most useful when using namespaced keywords) and treating :as as special would be surprising

Right,

(let [{:keys [:as]} {:as 'foo}] as)

I can see how this would be useful (and I have used it) with namespaced kws, but it's a bit more far fetched with non-namespaced kws.

That ship has also long sailed, it's been there for a long time and won't be changed.

It's a linter 🙂

Some people even prefer it over symbols, as it's easier to grep for keywords

Don't use non-namespaced keywords in :keys destructuring 🙂

We use it in our codebase at work almost everywhere

It can definitely be an optional linter

but it's very much a taste / preference thing

maybe mixed style in one destructuring can be seen as bad

but clj-kondo already catches this sillyness by reporting :as as an unused binding, so I think it's sufficiently covered

true.

Well, I learned a couple of things, amongst them, a function called ident? which was added in 1.9
