Although I liked this at first too, it seems to me it cannot be  
always implemented.  I was now trying to add a singleton to my  
library and I can't do it with headers alone.   I need to maintain  
the pointer to the global instance somewhere, and that means having a  
global variable which cannot be defined in a header (or otherwise  
you'll get duplicates).  Unless I'm missing something, that is...
