Note: you have to create the anonymous reference -- you can't just push a value if the key doesn't exist.

In perl you can ;-)

use strict; use warnings; use Data::Dumper; my %hash; push @{$hash{key}}, 'value'; print Dumper \%hash; __END__ $VAR1 = { 'key' => [ 'value' ] };

This nice feature is called "autovivification" and is quite useful most of the time.
