CoffeeScript 0.2.1: Significant Whitespace, Splats, Existence, Object Compre...

CoffeeScript 0.2.1 is out this morning, with a slew of language improvements over the previous gem. http://jashkenas.github.com/coffee-script/ * Python-style significant whitespace to delimit blocks (no more periods). * Better conversion of JS statements into expressions -- you can pass a try/catch right into a function, for example (not that it's a good idea). * Splats, for variable numbers of arguments in function definitions and function calls. * Object and Range comprehensions, to augment the existing Array comprehensions. * A Ruby-style block syntax for passing functions as the final argument. * The existence operator, which returns true if a variable is not null or undefined. * All functions are named functions, to help ease debugging. * Array splice literals, to complement the array slice literals. All of your feedback from the previous post has really helped shape the language. I'd love to hear more.
