18 # is not yet common in Chromium and for now we want it to be an optional | |
19 # tool for helping to find bugs, not something that actually changes | |
20 # the embedded JavaScript (making it harder to debug, for example). | |

22 # I used to run with '--warning_level VERBOSE' to get full type checking | |
23 # but there are enough limitations in the language and compiler that | |
24 # it doesn't seem worth the benefit (spent more time trying to apease | |
25 # the compiler and reviewers of my code than the compiler saved me). | |

27 # Enable support for property get/set syntax as added in ecmascript5. | |
