Overriding Rollup/Babel-compiled `export *` causes error

Re-exporting all exports of a module that was compiled with Rollup or Babel and overriding one of the exports causes a TypeError because Reify attempts to set a read-only property in the exports object. Reproduction repository: https://github.com/klaussner/reify-issue-236.

Rollup input:

export * from "fs";

Rollup output (Babel output is similar):

// rollup-output.js

"use strict";

Object.defineProperty(exports, "__esModule", { value: true });

var fs = require("fs");

Object.keys(fs).forEach(function(k) {
  if (k !== "default")
    Object.defineProperty(exports, k, {
      enumerable: true,
      get: function() {
        return fs[k];
      }
    });
});

If the output is used like this with Reify, a TypeError is thrown:

export * from "./rollup-output";
export const existsSync = ":)";

TypeError: Cannot set property existsSync of #<Object> which has only a getter
