是否有Raku方法可以将哈希值与其对分配并拆分？

Question

我目前正在尝试在数组中使用哈希来查找数组中每个特定项目的键和值。我能够做到这一点，当我没有对数组进行排序时，键和值都是分开的，但是当我创建一个排序的数组，例如：

my @sorted_pairs = %counts{$word}.sort(*.value);

它将值绑定在一起。是否有一种分类的哈希值方法可以将对分为数组中的单独实体？我希望能够分别访问“单词”字符串以及单词被视为整数的数量或次数。

我正在使用此 source 作为参考。我尝试了一些这些方法，虽然它似乎确实按数字值对数字进行排序，但给定输出：

排序的数组：[do =＆gt; 1 rest =＆gt; 1 look =＆gt; 1通缉=＆gt; 1 give =＆gt; 1 想象=＆gt; 2读=＆gt; 2授予=＆gt; 2 ever =＆gt; 2爱=＆gt; 2 gong =＆gt; 2 感觉=＆gt; 2表示=＆gt; 2喜欢=＆gt; 2 you =＆gt; 2 live =＆gt; 3写作=＆gt; 3 come =＆gt; 3 知道=＆gt; 3是=＆gt; 3妈妈=＆gt; 4]

它不会将密钥和价值与彼此分开。

raku中的单词计数

您可能需要将结果保存为（bag - ged） - 哈什阵列（Pairs？），然后打印出一个。

raku -e 'my @aoh = words.Bag.pairs.sort(*.values).reverse; \
        .say for @aoh;'  Ishmael.txt

示例输入（ishmael.txt）：

Call me Ishmael.  Some years ago--never mind how long precisely --having little or no money in my purse, and nothing particular to interest me on shore, I thought I would sail about a little and see the watery part of the world.  It is a way I have of driving off the spleen, and regulating the circulation.  Whenever I find myself growing grim about the mouth; whenever it is a damp, drizzly November in my soul; whenever I find myself involuntarily pausing before coffin warehouses, and bringing up the rear of every funeral I meet; and especially whenever my hypos get such an upper hand of me, that it requires a strong moral principle to prevent me from deliberately stepping into the street, and methodically knocking people's hats off--then, I account it high time to get to sea as soon as I can.

使用上面的代码获得以下输出（通过指定$_。value＆gt; = 4）截断了以下输出

raku -e 'my @aoh = words.Bag.pairs.sort(*.values).reverse; \
        .say if ($_.value >= 4) for @aoh ;'  Ishmael.txt
I => 8
the => 7
and => 6
of => 4
to => 4
a => 4

。通过将第二个语句更改为.keys.put @AOH：

$ raku -e 'my @aoh = words.Bag.pairs.sort(*.values).reverse; \
          .keys.put if ($_.value >= 4) for @aoh ;'  Ishmael.txt

I
the
and
a
to
of

或仅通过更改第二个返回。对.values.values.put @aoh：

$ raku -e 'my @aoh = words.Bag.pairs.sort(*.values).reverse; \
          .values.put if ($_.value >= 4) for @aoh ;'  Ishmael.txt

8
7
6
4
4
4
