Data Storage

You may have noticed that our Foo::Bar object is based on Perl's native hash datatype.  Because hashes provide an easy way to hold name-value pairs, it happens that they are very convenient for the type of data needed for most aggregate datatypes.

That being said, a Perl object can use any Perl datatype for its data storage.  If you object feels like an array, use one.

Basic objects are usually hashes, because they are flexible.
