Not so sure about aligning stuff with whitespace however. I the sense that symfony is going this way, but from my POV extra whitespace = more maintainance and makes coding less fluent / automatic - i.e. you have to hammer the space bar X amount of times until the line is where it should be, and then later you need to adjust the whitespace again when you make one of the array keys longer.  I think its aesthetics over practicality. Rant over :)
