Semantic indent and alignment

Use whitespace to communicate structural significance.
Popularity should not justify doing the wrong thing.  Such a deep indent wastes white space and encourages an inconsistent depth that is based on circumstances in the previous line. You have to resort to human parsing (time consuming) even in cases where you don't care to know the arguments.  It's much smarter to use a consistent the shape of the code to convey (at a glance) the structure of the construct.  The ruby community, and others, should consider that style deprecated for the reasons I've started here.
