Announcing CoffeeScript 2

I'm not a big fan of the new =>, it means the arguments variable will have parent scope in => but not in ->, it kind of erodes into coffeescript's elegance/consistency imho, unless I'm missing something ?

I never used => but when JavaScript introduced the fat arrow and made it different from the fat arrow in CoffeeScript, this introduced a mental barrier for me. By definition, the JavaScript fat arrow is the important one to know.

You can always add an splat to use instead of arguments:

    (args...) =>

Sure, but there used to be a strong performance advantage when using the arguments variable with function.apply, also editing arguments' values affected named parameters' values (not sure that's desirable, but you know, semantics)
