I use the following because it limits the scope of the two variables, $item and $hash_ref, to the loop where they are used. 

for my $item ( 0 .. $#{$ref} ) {
    $hash_ref = $ref->[$item];
    print "$hash_ref->{'key1'};
}

It also continues to work when you add extra code that includes a next or redo statement.

Update fixed code thanks to johngg. Teach me to post without running it first;)
