Just ignore, I don't play the semantics game well (you're right)
use anal::retentive;
Except that it's not. An object is nothing more than a blessed reference, not data structure. Observe:
my %foo = (1,2,3,4); bless %boo,'bar'; __END__ Can't bless non-reference value at - line 2.
Now you know I like to quote ;) from perldoc -f bless
bless REF,CLASSNAME
bless REF
        This function tells the thingy referenced by REF that it is now
        an object in the CLASSNAME package. If CLASSNAME is omitted, the
        current package is used. Because a "bless" is often the last
        thing in a constructor, it returns the reference for
        convenience. Always use the two-argument version if the function
        doing the blessing might be inherited by a derived class. See
        the perltoot manpage and the perlobj manpage for more about the
        blessing (and blessings) of objects.

        Consider always blessing objects in CLASSNAMEs that are mixed
        case. Namespaces with all lowercase names are considered
        reserved for Perl pragmata. Builtin types have all uppercase
        names, so to prevent confusion, you may wish to avoid such
        package names as well. Make sure that CLASSNAME is a true value.

        See the section on "Perl Modules" in the perlmod manpage.
update: hmm, it's a weird thing, the datastructure is "blessed", but only the reference knows, weird
