I'm designing a system that will be implemented in C++, although this 
question is probably language-independent.  At various points in the 
program, a method gets an object or structure passed to it (actually, 
for efficiency, a reference is used).  In many situations, passing an 
object's memory seems more appropriate than passing its address. 

Do any of you experts out there have any ideas about this?  When is it 
better to pass a handle, and when is it better to pass an address?
