should we have to use the bless fuction in the constructor alone???? we can
use the created object ($foo) to invoke the function. isnt it??? so whatz
the real advandage of using bless function??? and why we need to bless that
particular object to some specific classes...
I really dont understand the functionality and advantages of using bless.
Thank you
