Assigning to Undeclared Global Variable Must Throw Reference Error

[veera-sivarajan]

Describe the bug
In strict mode code, assigning to an undeclared global variable must throw a ReferenceError but Boa's runtime evaluates it without any errors.

This bug causes assign-to-global-undefined.js in test262 to fail.

To Reproduce

"use strict";

undeclared = (this.undeclared = 5);

Expected behavior
This should throw a reference error. Instead, 5 is assigned to undeclared and no error is thrown.

Additional context
I'd like to try and find a fix for this. Can you please assign it to me? Thanks!
