Fails on pure functions that are spuriously bound

[webbedspace]

Consider this code:
var x = function() { return 2; }.bind(this);
This incorrectly becomes const x = () => 2.bind(this);.

Thanks for reporting. That's quite an important bug.

Turns out to be a bug in recast: benjamn/recast#264

Hopefully Recast can fix it soon enough, so we don't have to create a workaround.

This is now mostly solved by simply removing .bind(this) from arrow functions. So the above code becomes:

const x = () => 2;

The issue still remains when one decides to call some other methods, like:

x = function(a,b){ return a+b: }.apply(this, [1, 2]);

This should be a fairly rare scenario, so waiting for Recast to fix their bug.

Hey @nene, you've got a nice project here! And my first contribution would be to fix this long standing bug in Recast :)

Thanks!
