Permit unicode escape sequences in keywords (thi\u0073 is a keyword, not an identifier)
This should be a SyntaxError: var thi\u0073; Currently we permit it and actually declare a variable named "this" (although we ban it in strict mode, apparently by accident rather than by design). See discussion here: https://mail.mozilla.org/pipermail/es-discuss/2011-June/015389.html The most persuasive response was Allen Wirfs-Brock's interpretation of ES5: https://mail.mozilla.org/pipermail/es-discuss/2011-June/015422.html No one really disagreed.
