Personally, I'm suprised this train has generated as much steam as it has. The emotional intensity of the commentary wars between the "Arc Sucks" camp and the "You suck for thinking that Arc Sucks" camp is perhaps higher than the situation warrents. Those who like it will use it even in the absence of some important features, those who don't certainly don't have to (I daresay there are plenty of other programming languages for them to use). :-)
