1) Strings are immutable.  This implies that there is zero 
practical difference between two references to two separate 
string objects of identical value, and two references to the same 
string object.

2) Keeping point #1 in mind, it is both faster and more memory-
efficient to use the same string object wherever practical.

3) Why on earth are you even worried about object identity for 
simple strings???  ;)
