Probably an asked question: How do I create a tied hash so that when I
retrieve the keys, I get it back in the order I inserted inside of TT2?.
Example:

[% hash = {
        one = 1,
        two = 2,
        three = 3
       };
%]

[% FOREACH key IN hash.list('keys');
     "$key\n";
     END;
%]

I'd like it to print
one
two
three

every time, deterministically. In regular perl, we use Tied hashes to
achieve this effect. How do I do this TT? Obviously, I don't want to use the
sort method, since my keys are random.

Thanks
Subbu
