Actively thinking about "live bindings" may honestly confuse the way you
think about imports. When you do
export var foo = "value";
then
import {foo} from "./foo";
console.log(foo);
Every time you access `foo` in the second module, you are literally
reaching into the first module to grab the current value of `foo`. You can
think of it like this, in CommonJS terms:
var foo = "value";
Object.defineProperty(exports, 'foo', { get(){ return foo; } }
and
var fooMod = require('./foo');
console.log(fooMod.foo);
so accessing the 'foo' export calls a getter method to access the current
value of `foo`, so any change to the value inside the first module will
immediately change the next time you trigger the getter.
