My Thoughts on this Feature

Solid gold money. Why they have yet to add this to Java is beyond me, and this is just extremely helpful. I don’t quite understand why I need _= instead of just =, but, whatever. This is a great feature. It’s even more compact than Ruby’s :attr_reader and :attr_accessor syntax.
