Code:
 
$cup = new Cocoa(1,2,3); # you can even pass the data from main program and that will be updated in doInitialization().
 
Just FYI.
 
We can even create object with the below syntax.
 
$cup = Cocoa->new(1,2,3);

'my' variables are not accessible unless you blessed to your object or make that variable to 'our'. But 'our' variables exist through out the program and occupy some memory space.

So, If you want you program to be more optimized, you should return the objects(variables/hash/array) from you function to the main program and use from there.

Does this makes sense?

Please use code tags Smilie

	   $message = "";      #not ok
	   $message = "     "; #not ok

	   $message = q{};     #better
	   $message = q{     } #better

	   $EMPTY = q{};
	   $message = $EMPTY;	   #best

	   $SPACE = q{ };
	   $message = $SPACE x 5;  #best
