Is it possible to include Number polyfills?

Everything except the constructor since that would break match()

This is most likely an issue w/ Babel, and may be related to this issue, but I wanted to post this to see if someone might be able to help me.

Say I have the following classes defined:

A = class A {
    constructor(value, options) {
        this.value = value;
        this.options = options;
        console.log('constructor this: ', this);
    }

    get value() {
        return this._value;
    }

    set value(value) {
        this._value = value;
    }

    get options() {
        return this._options;
    }

    set options(options) {
        this._options = options;
    }

    get validationErrors() {
        // Do standard validations for all classes of type A here
        console.log('A.validationErrors this: ', this);
        var validationErrs = [];
        if (options && options.required && !value) {
            validationErrs.push('Value is required');
        }

        return validationErrs;
    }
}

B = class B extends A {
    get validationErrors() {
        console.log('B.validationErrors this: ', this);
        var valErrs = super.validationErrors;
        // Do custom validations for class B here
        return valErrs;
    }
}

var b = new B('val', {required: true});
var valErrs = b.validationErrors;

Strangely, what I see in the logs is:

constructor this: B{_value: "val", _options: {required: true}}
B.validationErrors this: B{_value: "val", _options: {requried: true}}
A.validationErrors this: A{}

Furthermore, if I call this.value or this.options in the parent's validationErrors, I end up with undefined returned. It seems like the constructor and getters are being copied down, at least in behavior, but they shouldn't be, right? I would think that the child's constructor would simply call the parent's in this case, but that doesn't seem to be happening.

Hello,

Hi, im having some trouble with transpiling my code to ES5. When i build with --production flag my meteor application it runs OK on chrome and firefox, but when i run it on safari it returns this error:
"SyntaxError: Cannot declare a let variable twice: 'e'."
In this place of the code ( which is some meteor code )

I know this error is a bug already reported from safari, but my question is: the let statement is a ES2015 feature, why is it not being transpiled to a var?

Meteor @ 1.2.1
ECMAscript @ 0.1.6 (Can't upgrade to 0.3 because unversioned Accounts package depends on 0.1.6)
MacOS @ 10.11.2
Safari @ 9.0.2
