New addition to my hash keeper:
"returns" hash on a sub declaration:
Note: "Associative" will return a hash or a map or even a pair

&x

{A => a}

&x

Yeah, and even a 1024-digit integer, or much larger, if so you wish.
I love it!

Perhaps I have some questions to help improve the docs (I think):
1- You told about arrays of hashes, in Perl5 the opposite (hashes of
arrays) is quite fuzzy. Then, in Raku, how do I deal with hashes of arrays?
2 - "[...]say %h

A recent addition to my hashes keeper:
Confining hashes:
Note: as of 2020-01-15, confining only works with Str.
And you must confine the entire hash, not each member
my Str %h = A => "a"
{A => a}
my int %h = A => 123
