It used to be like that once upon a time, but we later changed it

NP, it’s a good way for me to pick up the disparate Perl 6 clues
I picked up haphazardly over time, too.

Wrt your second problem, if this

is not rw so is not actually adding the entry to the hash (btw,

Just curious does this actually run? I'm trying on pugs 6.2.11 and it complains
quite a bit. First of all shouldn't
for %buckets.values -> $arg_for
be
for %buckets.values -> $arg_for is rw
since $arg_for is modified?
And then I get an error telling me 'No such method in class Scalar: "&kv"'
Hi Everyone,
I never thought that my little script would get such loving
attention least of all from such distinguished members of the
community. It took me a little while to understand exactly what was
going on but now that I do, it looks very good.
Thank you again! It has been very ins

You should not need "my" on the right side of a ->. Also, you should
be able to write $arg_for for constant subscripts.

Thanks! The revised script is below for those who are interested.

Hi Chris,
I hope you don't mind. With the idea of getting back into Perl6, I've taken
the liberty of rewriting your code to clean it up a bit (somewhat
successfully), and make it more "perl6ish" (somewhat unsuccessfully). The only
significant issue I have with my version is the terribly neste

First the Perl6-equivalent of
$" = '|' ;
and then
say "@array" ;

Dear Mr. Bach,
You were indeed correct so I wrapped the %hash like this
"@{%hash}" like you would to de-refrence an array and it worked
perfectly. It was indeed just me.
Thanks to everyone that responded!

my (@array) = 1,2,3;

It prints
1|2|3
on my terminal.

I would say something like:
print $array[0] . "|" . $array[1] . "|" . $array[2] . "\n";
not the best way but it works.
In Perl6 if say something like this:
print @array[0] ~ "|" ~ @array[1] ~ "|" ~ @array[2] . "\n";
I get
