Itemization helps: m: my %h = x => 6, y => 7; my @a = $%h; say @a[0] rakudo-moar 0132b6: OUTPUT«x => 6, y => 7␤» m: my %h = x => 6, y => 7; my @a; @a.push: $%h; say @a[0] rakudo-moar 0132b6: OUTPUT«x => 6, y => 7␤» Am 26.09.2015 um 07:58 schrieb Gabor Szabo: > In the first two cases the hash

How to push a hash on an array without flattening it to Pairs?

In the first two cases the hash was converted to Pairs before assigning to the array. Only the third case gave what I hoped for. How can I push a hash onto an array as a single entity? use v6; my %h = x => 6, y => 7; say %h.perl; # {:x(6), :y(7)} my @a = %h; say @a.elems; # say @a[0];
