Neat! tobyink++

All I need now is something like, say feature::each_on_array, so that the code below: 

use feature::each_on_array;
@a = (1..1000);
while (my ($idx, $item) = each @a) { }

will run on Perl 5.10 and will take no performance hit on 5.12+.

Are you interested in packaging Tie::ArrayAsHash for distribution? There's already Tie::Array::AsHash on CPAN. Perhaps rethink the name because your solution also provides aeach(). 

package feature::each_on_array;

use strict;
use warnings;
use Tie::ArrayAsHash qw(aeach);

sub import {
    return unless $^V lt 5.16.0;
    no strict 'refs';
    my @caller = caller;
    *{"$caller[0]::each"} = \&aeach;
}

1;
