Why would you want to do that when Perl offers arrays of hashes? In the POD, the Perl Datastructure Cookbook ought to get you going along those lines. Imagine a datastructure that looks like this (pseudocode):

@lookup = (
    { 
        id         => value,
        another_id => value,
    },
    {
        id         => value,
        #etc
    }
);

With that structure, you could access the inner hashes like this:

my $value = $lookup[0]->{id};

What you're asking can be done, but should not be done. You don't have one of those extremely rare special cases that justifies using symbolic references. Real references are a better way to accomplish the task you're trying to achieve.
