$ clj
Clojure 1.10.1

seems like a bug?

A JIRA issue was raised about it three years ago @thheller

do you happen to have a link to that? I was looking the other day and couldn't find it

https://clojure.atlassian.net/projects/CLJ/issues/CLJ-1966

thanks

It came up on the mailing list just a few days ago which is why I remembered it... and why I couldn't find it searching Slack or Zulip! 🙂

ah right. my search failed because the ticket uses :clojure.spec/invalid

I should prob just close that as won’t fix

There are workarounds for all the situations I’m aware of like this and it’s I think nontrivial to “fix”

Like in the example above you can def a var to the invalid keyword and then use the var instead

yeah, I suggested that too

thx

Ah, the ticket predates Spec being broken out of Clojure 1.9 into the separate alpha package? (or is it just a typo)

Predates

I think
