| michael@0 | 2 | * Check that builtin character classes within ranges produce syntax |

| michael@0 | 4 | * |
| michael@0 | 5 | * Note that, per the extension in bug 351463, SpiderMonkey permits hyphens |
| michael@0 | 6 | * adjacent to character class escapes in character classes, treating them as a |
| michael@0 | 7 | * hyphen pattern character. Therefore /[\d-\s]/ is okay |
| michael@0 | 8 | * |
| michael@0 | 9 | * Note: /\b/ is the backspace escape, which is a single pattern character, |
| michael@0 | 10 | * though it looks deceptively like a character class. |
