+ * ```javascript
+ * const { exports: moduleExports } = evaluateModuleFromSource("const foo = 7;\n module.exports.bar = 10 + foo;");
+ *
+ * assert(moduleExports.bar === 17);
+ * ```
+ *
+ * @param {String} source to be evaluated using Node's `vm` modules
+ * @param {{ require: Function }} options used in the context during evaluation of the Node module
+ * @returns {{ exports: any }} exports added to the script's `module.exports` context
