IOCCC winners announced

2013 IOCCC winners announced. ( http://ioccc.org )

This is usually a depressing event for me because it's always been my dream to compete in one of these (although I officially realized I never will after toledo of 2005), but this year was especially bad. Endoh and Cable, man.

#define i(B,M)B(o){return M;}
This is the first time I see a macro like this. How is this even parsed?
