in reply to Using foreach to process a hash

You could use foreach to iterate over the keys or values, or you could use a while loop and each. 
my %hash = ( a => 1, b => 2);
while (my ($key,$val) = each %hash) {
  print "$key = $val\n";
}


for my $key (keys %hash) {
  my $val = $hash{$key};
  print "$key = $val\n";
}

    Note: You can't safely use last, return or die to exist a while each loop. Not running each to the end makes each unusuable on that hash at a latter point. While less memory efficient, the for alternative avoids this problem.
