[plt-scheme] match.ss questions

I have just gotten around to trying to use match.ss, and it is quite 
nice. I am using it in Pretty Big, where it is automatically loaded. Can 
someone explain why I cannot use false or empty in patterns, but have to 
use #f and '() instead? Also, why is match.ss automatically loaded, and 
not plt-match.ss? (I know I can just require it, but I am thinking about 
students.) Thanks. --PR
