From my current understanding (based on other threads), this module:
```js
var foo = 42;
export default foo;
export foo;
foo = 10;
I guess you'd intended to write `export {foo as default}` instead of `export default foo`, because
the latter exports the value of the expression when it gets evaluated. IOW it's the same as `export
default 42`.
However, I am curious if this binding is 2-way or only 1-way. What happens if I
do:
```js
import foo, * as FOO from "coolmodule";
foo = 100;
FOO.default = 200;
FOO.foo = 300;
All three assignments throw a TypeError exception:
- The first assignment throws a TypeError in 8.1.1.1.5 SetMutableBinding, step 6. (Import bindings
are immutable - 8.1.1.5.5 CreateImportBinding, step 5.)
- The second and third assignment throw a TypeError in 6.2.3.2 PutValue, step 6.d. (Module namespace
objects always return false from [[Set]] - 9.4.6.9 [[Set]].)
