Anyone know of one or more lib(s) that add back more traditional imperative/mutable constructs to Clojure? Sometimes I want to freshen up on leetcode and stuff to keep my interviewing game on, and would still rather do it in Clojure, but I also want to solve them with the imperative mutable solutions. So, I guess I'm thinking traditional for-loop, while-loop, do-while, mutable local vars, etc. I can use Java data-structures so that part is fine.

I also just realized this doc: > Symbols beginning or ending with ':' are reserved by Clojure. A symbol can contain one or more non-repeating ':'s. > Why does Clojure reserve symbols that end with : ? I don't think there's any use of that right now correct?

In order to add more features to the language sometimes it is necessary to reserve behavior as disallowed even if it doesn’t currently do anything. if :bob: was a legal keyword now, they could never make it a different construct in the future without breaking existing behavior

True, I think it just made me curious, they didn't reserve much, but specifically colon at the end, like they already had an idea for it 😉 I always thought it be nice if the syntax for keywords allowed for the colon at the front or at the end.

{name: "John"}
(= :name name:) ;=> true

So it got me curious if this was why they reserved it

I am writing a macro for a library. What’s the metadata to add to the macro so as to customize the indentations of macro arguments?

pinkfrog13:08:11

Yes. I am aware of this, but that somehow get ignored by caval (and cljfmt).

didibus17:08:00

Don't think there's a universal standard across all tooling.

pinkfrog00:08:37

I want something working with calva/cljfmt only as this is what our team members are using.

Joshua Suskalo00:08:28

cljfmt doesn't work with meta and provides no way to distribute indentation specs.
