| 153 | | * <https://bugs.webkit.org/show_bug.cgi?id=149338> Currently, arrow functions will always capture lexical `this`, even if the arrow function does not actually use `this`. The behavior causes TDZ error if such an arrow function is used in a constructor before calling `super()`. |
| 154 | | * Only basic functionality is implemented. Lexical binding of `arguments`, `super`, `new.target`, and `toString` are unimplemented. |
