clojure - 使幽灵返回（部分）所选路径

Question

在以下结构中，我知道如何遍历:x的所有子项的值:whatever：

=> (specter/select
       [:whatever specter/MAP-VALS :x]
       {:whatever {:a {:x 1} :b {:x 2}}})
[1 2]

我想得到的是类似于以下内容的内容，其中包含通配符映射键。

[[:a 1] [:b 2]]

幽灵怎么能做到这一点？

(select
        [:whatever ALL (collect-one FIRST) LAST :x]
        {:whatever {:a {:x 1}
                    :b {:x 2}
                    :c {:x 55}}})
=> [[:a 1] [:b 2] [:c 55]]
