Hello! Is this intended?

$ npx squint -e '(pr-str js/undefined)'
file:///home/chrism/dev/eucalypt/node_modules/.pnpm/squint-cljs@0.9.183/node_modules/squint-cljs/src/squint/core.js:3026
  return `#object[${value.constructor.name}]`;
                          ^

TypeError: Cannot read properties of undefined (reading 'constructor')

Amazing, will test, thank you!

If found another weird one. (I'm upgrading Squint to latest in Eucalypt). A lazy sequence inside and/or/cond causes the Vite compiler to throw an error. Apparently this is not valid JS syntax (although Node runs it, Vite does not like it):

12: if (squint_core.truth_((alive_QMARK_5 && yield* ((function* () {
                                             ^

This was working in 0.9.174 so I guess something changed to do with generators.

borkdude 2026-01-24T14:51:23.016759Z

oh that's bad

borkdude 2026-01-24T14:51:28.463779Z

repro welcome

borkdude 2026-01-24T14:51:40.392879Z

I did some optimizations that were probably too dangerous

Chris McCormick 2026-01-24T14:51:42.866719Z

There's a repro in the issue that should hopefully be simple to deploy.

Chris McCormick 2026-01-24T14:51:55.265339Z

You create two files in a directory and then run squint and then vite.

borkdude 2026-01-24T14:52:17.614399Z

ah you already made an issue, great
