Yeah, it's a syntactic shortcut, but one click init is also possible  
using sends.

Nice patch, that's a substantial difference.  I got 80 for sendsends  
and 150 for msgsends.

Terrorism is not an enemy.  It cannot be defeated.  It's a tactic.   
It's about as sensible to say we declare war on night attacks and  
expect we're going to win that war.  We're not going to win the war  
on terrorism.        - retired U.S. Army general, William Odom
