Subject: Re: Subselecting hash back into hash (oneliner?)

Nice .. well that works :-) but in the constructor can you tell me  
what "*" would literally "mean"?

Does this just take only an Array obj or could you place any object  
in there w/ public attributes/methods?

(Was this covered in pick-axe somewhere I missed?)

Thank you, much appreciated ...
