Hi Fernando,

You called it.  I had to declare @y first before
assigning hashes to it.

Thank you!

$ p6 'my @y; @y[0]={a=>"aa",b=>"bb"};'

Try:

p6 'my @y; @y[0]={a=>"aa",b=>"bb"}; push @y, {a=>"AA",b=>"BB"}; for @y.kv
-> $I, $J { say "Index $I  $J  $J" }; say "elements " ~ @y.elems;'

You can't write "my @y[0]".

Hi All,

What am I doing wrong here?

$ p6 'my @y; my %x=(a=>"aa", b=>"bb"); @y[0] = %x; %x="AA"; 
%x="BB"; push @y,{%x}; for @y.kv -> $I, $J { say "Index $I  $J 
$J" }; say "elements " ~ @y.elems;'


Index 0  AA  BB
Index 1  AA  BB
elements 2


It should be

Index 0  aa  bb
Index 1  AA  BB
elements 2


Many thanks,

okay, I got this far:

$ p6 'my @y; push @y, {a=>"aa",b=>"bb"}; push @y, {a=>"AA",b=>"BB"}; for 
@y.kv -> $I, $J { say "Index $I  $J  $J" }; say "elements " ~ 
@y.elems;'


Index 0  aa  bb
Index 1  AA  BB
elements 2


But I still have to figure out how to

@y[0]={a=>"aa",b=>"bb"}

$ p6 'my @y[0]={a=>"aa",b=>"bb"}; push @y, {a=>"AA",b=>"BB"}; for @y.kv 
-> $I, $J { say "Index $I  $J  $J" }; say "elements " ~ @y.elems;'
