@ljharb Yes `f.call()` has an `undefined` receiver but I think `f.call`, `f.apply` or `f.bind` are some degree reflection APIs like `Reflect.apply(f, undefined)`, programmers only use them for specific reasons, most...

If never trigger, we'd better forbid it in syntax layer? Since you can't write ```js function f(x = foo) { 'use strict' //
