Lately, it seems like I can never tell whether anyone's being serious or not 
online. :)

LOL. Personally, I actually think that the Java 7 syntax looks great (I'd 
never seen it before), but catch(e : Ex1, Ex2) is just as good and more 
consistent with the language as a whole, since it doesn't try to give any 
operators a new meaning (as Java's does).
