Why I hate Coffeescript.

gistfile1.txt

a = undefined   # var a;
a = "lol"       # a = 'lol';
rawr = (->      # rawr = function() {
  a = "wat"     #   var a = 'wat';
  a             #   return a;
).call()        # }.call();
console.log a   # console.log(a);
# returns 'wat' # returns 'lol'
# What the fucking fuck, Coffeescript...

Wait, I am totally confused. Do I see this right that with "returns" you mean that that's what the console.log prints not what the return value of rawr would be if called? If that's the case then the coffee version makes absolutely no sense. Not only did they break variable scope, but also method invocation/definition. It's so broken, I am not even sure what they broke.

@ajmurmann, it's showing that coffeescript doesn't use var within function definitions. They don't like var.
