Clojure 异步放置！ return 值
Clojure async put! return value
Clojure async put! docs 说（强调）
Asynchronously puts a val into port, calling fn0 (if supplied) when
complete. nil values are not allowed. Will throw if closed. If
on-caller? (default true) is true, and the put is immediately
accepted, will call fn0 on calling thread. Returns nil.
然而示例代码returns true
user=> (put! c "XYZ")
true
文档不正确还是我遗漏了什么？
这已在 this commit 中修复，新的文档字符串为：
"Asynchronously puts a val into port, calling fn1 (if supplied) when
complete, passing false iff port is already closed. nil values are
not allowed. If on-caller? (default true) is true, and the put is
immediately accepted, will call fn1 on calling thread. Returns
true unless port is already closed."
