This is not a hash table. This is a series of assignments of values to four independent variables. At most, this looks like an array broken up into pieces ...

It's most likely this:

use Data::Dumper;
my %hash = ( key_1 => 'value_1', key_2 => 'value_2' );
print Dumper(%hash);

__END__
$VAR1 = 'key_2';
$VAR2 = 'value_2';
$VAR3 = 'key_1';
$VAR4 = 'value_1';

Better would have been print Dumper(\%hash);
