this is in response to BOTH of your postings. please even quote yourself
if you have to do this.

you can use ANY reference for an object, not just hashes. hashes just
are the most common and usually direct way to do perl objects. get the
book Object Oriented Perl by damian conway and learn how to make objects
out of any ref including arrays. that will also show you how to
initialize them (hint: just the same as with any array you need to
init).

That is an excellent solution if the array is the only data to be
kept in the object. If the array is just one field among others,
there is no other way than than to use an arrayref much like the OP
did.
