The alternative here is:

    function MyThing() {}
    export { MyThing as default };

Which is more clear, more readable, and barely less ergonomic.  If you
*really* want the AssignmentExpression form, you've got to put the equals
in there.  I've said this before, but without the equals it looks too much
like a declaration:

    export default class C {}
    var c = new C(); // No C defined, WTF?

Node users don't elide the equals sign, do they?

    module.exports = whateva;

So why are we?

Equals aside, let's look at the cost/benefit ratio here:

- Benefit: a little less typing (at most one savings per module)
- Cost: more confusion and StackOverflow questions about default export
syntax.
