Most monks would suggest the more natural foreach for something like this, as it tends to cut down on "one-off" errors. Also, it tends to be more intuitive (at least after you've learned Perl; I can see how your way would be more intutitive to a person coming from C or Java).

foreach my $href ( @data ) {
    for ( keys %$href ) {
        print "$_\n";
    }
}
