Not necessarily.  I don't know how arrays are actually implemented,  
but given that they are reference-counted things with methods and  
properties, my guess is that they have a similar amount of memory  
overhead.  My suggestion would be to write the interface you want,  
then provide a simple implementation that works.  Now you have a  
baseline against which to measure your performance anxiety.  The Pair  
class is already written, so why not use it?
