if it makes you happy, define it as %self = ( )
the point is, you have to bless (and even more, RETURN) a reference, so
sooner or later, you'll have to say
\%self anyway... might as well start with declaring as a reference....

doesn't matter... the , allows for appending more entries... after the last
entry you dont *need* it anymore, but it does no harm
