<pre>For example:
(function (x = 1) { return arguments.callee })() // should throw, even in sloppy mode
For reference, see step 22 of: <a href="http://www.ecma-international.org/ecma-262/6.0/#sec-functiondeclarationinstantiation">http://www.ecma-international.org/ecma-262/6.0/#sec-functiondeclarationinstantiation</a>
In short, the spec recognizes two types of Arguments objects:
* mapped Arguments object, used for sloppy-mode simple-parameter-list functions;
* unmapped Arguments object with poisoned `callee`/`caller`, used for anything else.</pre>
