Arrow binding with 1 argument #10

Closed geelen closed 10 years ago

geelen commented 10 years ago

All arrow functions bind this, even with only one argument:

x => x + this.y needs to compile to:

function(x) {
  return x + this.y;
}.bind(this);

This fixes that, and even has tests!

Awesome, thanks! I actually noticed that before but hadn't pushed a fix. Thanks for including tests & fixing up the other stuff!
