Thanks for the new method!

In fengari we currently use https://github.com/fengari-lua/fengari-interop/blob/8e59efb7...

    const global_env = (function() {
        /* global WorkerGlobalScope */ /* see https://github.com/sindresorhus/globals/issues/127 */
        if (typeof process !== "undefined") {
            /* node */
            return global;
        } else if (typeof window !== "undefined") {
            /* browser window */
            return window;
        } else if (typeof WorkerGlobalScope !== 'undefined' && self instanceof WorkerGlobalScope) {
            /* web worker */
            return self;
        } else {
            /* unknown global env */
            return (0, eval)('this'); /* use non-strict mode to get global env */
        }
    })();

I created https://github.com/fengari-lua/fengari-interop/issues/45 to track.
