+                 * In the original version of this package, this was:

+                 *
+                 * Unfortunately LavaMoat trips up on this, so we have to change
+                 * it.
+                 *
+                 * Internally LavaMoat uses `lockdown` (part of SES, which is
+                 * part of Endo) to freeze modifications to "intrinsics" — core
+                 * things like `Object.prototype`, `Function.prototype`, etc.
+                 * This will cause code which is responsible for said
+                 * modifications to fail at runtime, because it makes the
+                 * properties of these intrinsics non-writable.
+                 *
+                 * The reason we have to change *this* code is that later on,
+                 * this `__assign` function is used to merge two objects, and
+                 * one of those objects contains a `constructor` property. As we
+                 * know, `constructor` is a special property, as it's a property
+                 * on `Object.prototype` that stores the constructor used to
+                 * create that object. But when used in this context, there is
+                 * nothing inherently special about it – it's just a property on
+                 * an object we're setting. Unfortunately, that's not how it's
+                 * being treated. Because `lockdown` freezes `Object.prototype`,
+                 * `Object.prototype.constructor` is non-writable, and due to a
+                 * "mistake" in the ES5 spec [1], that means `constructor` on
+                 * *any* object is non-writable too. So an error is thrown when
+                 * this code is executed.
+                 *
+                 * There is a way to get around this, which is to configure
+                 * `lockdown` with the option `overrideTaming: 'severe'`.
+                 * The mechanics of this option, as well as more information
+                 * about the "mistake" this option solves, are explained here
+                 * [2]. Unfortunately, we cannot enable this option because
+                 * LavaMoat is the one running `lockdown` here [3]. So to work
+                 * around this, we use `Object.defineProperty` to define the
+                 * property we want. As this does not use property assignment
+                 * (`object[key] = value`) but rather defines the property more
+                 * directly, this bypasses the "override mistake".
