Purely for completeness.

Option 1: 

while (@ref) {
  my $k = shift(@ref);
  $out{$k} = [ shift(@ref), shift(@ref) ];
}

or if the temporary bothers you: 
while (@ref) {
  $out{$_} = [ shift(@ref), shift(@ref) ] for shift(@ref);
}

Option 2: Change your SQL to something like SELECT key, value1, key, value2, then do: 

push @{ $out{shift(@ref)} }, shift(@ref) while (@ref);

Personally, I'd stick with your original.
