Another one is that "$" is meant to be used to "compress" vertically any deeply-indented code that happens to be just monotonically indenting more. So: foo ! bar ! ! nitz ! ! ! quux meow is the same as: foo $ bar ! nitz ! ! quux meow is the same as: foo $ bar $ nitz ! quux meow And is the same as: foo $ bar $ nitz $ quux meow And then there's the form: foo ! bar is the same as: foo $ bar is the same as: (foo bar) ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
