I think that's actually disrecommended, because it looks too much like 
Perl 5's refs but isn't, so it can bite you unexpectedly if you treat it 
like one.


okay, but I don't know how to di it in Perl 5, so ...

P6's sub declarations are so much better than P5's it take
my breath away.

This seems too easy.  I have to have done something wrong.
What did I miss?


Only that it's even easier than you think: the @ was unnecessary when 
building it. Perl 6 handles this kind of thing much better than Perl 5. 
And there are other ways to spell the destructuring as well.


     pyanfar Z$ 6 'my %x = [aaa => "x", b=>["y","q","r"], c=>"z"]; say 
%x; for %x[*] {say $_};'

     {aaa => x, b => [y q r], c => z}
     y
     q
     r


Thank you!

Hi All,

I am creating a hash.  One of the keys I want to point to an array,
not a string.

I have created a test:

$ perl6 -e 'my %x = [aaa => "x", b=>@["y","q","r"], c=>"z"]; say %x; for 
@(%x) {say $_};'

{aaa => x, b => [y q r], c => z}
y
q
r

This seems too easy.  I have to have done something wrong.

Way to easy.

$ perl6 -e 'my %x = [aaa => "x", b=>@["y","q","r"], c=>"z"]; push 
@(%x), ""; say %x; for @(%x) {say $_};'

{aaa => x, b => [y q r ], c => z}
y
q
r



I am very suspicious.
