Hi, all. I've got two hashes created from external sources: $foo{$i}{$j} and $bar{$i}{$i} I need to know if there are any matches between foo & bar, for all $i & $j. Currently, I've 4 nested foreach loops: 
foreach i in foo
  foreach j in foo
     foreach i in bar
        foreach j in bar
          COMPARE

is there a better way of doing this? (the code above works but ugly)

Thank you.
