The bug: http://code.google.com/p/v8/issues/detail?id=2892
The spec:
http://people.mozilla.org/~jorendorff/es6-draft.html#sec-names-and-keywords
Particularly:
IdentifierStart ::
UnicodeIDStart
$
_
\ UnicodeEscapeSequence
I can't speak to U+2E2F particularly; mathias probably knows more.
ES5 used to specify `IdentifierStart` and `IdentifierPart` based on a list
of
Unicode categories, one of which (`Lm`) happened to include U+2E2F. But ES6
(mostly) just refers to `ID_Start` and `ID_Continue` instead.
U+2E2F has the `Pattern_Syntax` property and is thus not a valid `ID_Start`
code
point.
