ReferenceError using class

[sgodwin424]

The following code example:

class Test {
    fn() {
        let var1 = 'test';

        this.fn2((value) => {
            var1 = value;
        });
    }

    fn2(callback) {
        callback('value');
    }
}

new Test().fn();

produces the following error when it is ran with this plugin:

C:\Users\Scott\documents\github\test\foo.js:8
    var1 = value;
         ^

ReferenceError: var1 is not defined
    at _ref3 (foo.js:6:13)
    at Test._ref2 (foo.js:11:9)
    at Test._ref (foo.js:5:14)
    at Object.<anonymous> (foo.js:15:12)
    at Module._compile (module.js:425:26)
    at loader (C:\Users\Scott\documents\github\test\node_modules\babel-register\lib\node.js:128:5)
    at Object.require.extensions.(anonymous function) [as .js] (C:\Users\Scott\documents\github\test\node_modules\babel-register\lib\node.js:138:7)
    at Module.load (module.js:356:32)
    at Function.Module._load (module.js:313:12)
    at Module.require (module.js:366:17)

The exact same error happens when using a promise instead of a callback and when a regular function is used instead of an arrow function.
