That's a nice page! But I doubt that developers will create such tools often enough to make a convenience function in the standard worthwhile. I proposed isIdentifierStart and isIdentifierPart because recognizing identifier characters across ECMAScript and Unicode versions requires large data tables; implementing the unescaping rules and filtering reserved words isn't all that hard.
