Need explanation on Anonymous hash in PERL!!

Hi,

I have doubt regarding the Anonymous hash. For creating a object we are generally using Anonymous hash.
My Doubt is:
Why we are only using Anonymous hash?? Instead of Anonymous hash can we use global hash variable and take its reference for creating an object using same bless function?? What is the main reason behind using Anonymous hash only.

Any help on this regard is Welcome!!

Thanks in Advance.
