我无法将 #inst 值添加到 var 元数据中。编译失败，出现错误 不受支持：类 java.time.Instant
重现步骤
$ mkdir src
$ echo '(ns core) (def ^{:time #inst "2023-10-07"} foo :foo)' > src/core.cljs
$ clj -Sdeps '{:deps {org.clojure/clojurescript {:mvn/version "1.11.60"}}}' -M --main cljs.main --compile core
预期：编译成功
实际情况
Unexpected error compiling at (REPL:1).
Not supported: class java.time.Instant

分析
CLJS-3291 将 #inst 读取器更改为生成 java.time.Instant 而不是 java.util.Date。分析缓存转存写器无法写入 java.time.Instant，因为它只知道如何序列化 java.util.Date。
解决方案
(def foo :foo)
(alter-meta #'foo assoc :time #inst "2023-10-07")
