2 * Check that builtin character classes within ranges produce syntax
3 * errors.
4 *
5 * Note that, per the extension in bug 351463, SpiderMonkey permits hyphens
6 * adjacent to character class escapes in character classes, treating them as a
7 * hyphen pattern character. Therefore /[\d-\s]/ is okay
8 *
9 * Note: /\b/ is the backspace escape, which is a single pattern character,
10 * though it looks deceptively like a character class.
