Re: WIP: Access method extendability

Code looks much better now, thanks. Still I believe it could be improved.

I don't think that using srand() / rand() in signValue procedure the
way you did is such a good idea. You create a side affect (changing
current randseed) which could cause problems in some cases. And there
is no real need for that. For instance you could use following formula
instead:

hash(attno || hashVal || j)

And a few more things.

This looks a bit redundant.

More idiomatic Perl would be `for my $i (1..10)`.

In general I don't have anything against goto. But are you sure that
using it here is really justified?
