Yeah,

$tests{2} = \%blah2;

is the same as

$tests{2} = { 
              condition => "AND",
              terms => [ "foo", "bar" ],
            };

One thing that you should note is that when explicitly defining hashes and arrays, one can use "()"'s.

my @array = ( 1, 2, 3 );
my %hash = ( A => 1, B => 2, C => 3, );

However, anonymous arrays are defined with "[]"'s

my $array_ref = [ 1, 2, 3 ];
my @array = @{$array_ref}; # becomes an explicit array

and anonymous hashes are defined with "{}"'s.

my $hash_ref = { A => 1, B => 2, C => 3, };
my %hash = %{$hash_ref}; # becomes an explicit hash
