757273 - |arguments| in a destructuring pattern in strict mode code should be a syntax error

Status: RESOLVED WORKSFORME

(Core :: JavaScript Engine, defect)

Description

[Jeff Walden [:Waldo]]

function f() { 'use strict'; [arguments] = [0]; }

This should be a syntax error at parse time, and it definitely shouldn't change the value of |arguments| at runtime as it does now.

js> function f() { 'use strict'; [arguments] = [0]; }
typein:1:30 SyntaxError: can't assign to arguments in strict mode:
typein:1:30 function f() { 'use strict'; [arguments] = [0]; }
typein:1:30 ..............................^


Seems to be working like intended.

No longer reproducible - resolving as WFM.
