Unfortunately, for extreme inputs, the behavior turns out to be system-dependent; the unchecked casts intentionally map (nearly) directly to go casts to rune (there's a stop at int64 in-between). These tests are a modified version of Clojure's numbers tests, and on the JVM you can expect consistent behavior. This operation does not behave consistently across systems in Go. For instance, running on my m1 mac, the result is (Char -1).

The right approach here might be one of:

  1. Introduce a new :skip expectation; ignore cases whose expectation is :skip. Leave comments with reasoning.
  2. Support system-dependent expectations

2 is interesting, but there's no great way to be exhaustive. 1 seems adequate. What do you think?

Honestly I just wanted to not see the failures for these when running make test. Now I don't and the CI is green.

I'd be fine with just disabling these tests for now. Maybe comment them out with TODO text explaining why.

BTW, I'm close to submitting a PR that fixes issues with basic sort and sort-by. Just adding more tests.

I'm in the Clojure slack, if you want to chat more easily :)
