@dotnet-bot test Windows arm_debug please |

@pleath Thanks, I'm logging into the VMs to take a look. |

@dotnet-bot test Windows arm_test please |

@pleath Thanks. Looking into these as well. Not sure I'm seeing a pattern yet. |

@dotnet-bot test OSX osx_osx_debug_static please. |

There was a problem hiding this comment.
will it handle the case as
[o.x] = [function() {...}];
?

No, it won't. It's not actually meant to be exhaustive, just a cheap pattern-match to catch a certain common class of cases.

Other than few clarifications code wise looks good to me. |
function(){...}', 'o[s] = function(){...}', or 'return f(){...}'. Doing so at parse time allows us to disable stack-nested-functions in common cases where an escape is not detected at byte code gen time because of deferred parsing.
