Nested loop

[yitzle]

I got an array of hashes so I am using a foreach (@arr) loop to access
the hashes.
How do I go about looping through the hash's keys/values? I was
thinking of another foreach, but then the $_ gets a bit screwed up...

Do I need to do this ?
foreach(@arr) {
 %hash = %{$_};
 foreach (keys %hash) {
   print "$_ => $hash{$_}\n";
 }
}
