I filed the original bug, and I did not test anything but 9k. The bug was filed to capture an new spec failure when we last updated. In 1.7.18, it does look broken: |

@enebo So I'm not sure what to do here. This is a bug, MRI acknowledged it as a bug, but it was unfixed until 2.2. If we fix this on 1.7 branch, our local_variables behavior would not match 1.9.3. |

Then I think we leave it broken. That tells me no one likely has depended on this not being unique. I bet people who do this and care menually uniq the elements already. They definitely would if they want it to keep working between versions. |

Fixes #2129 by removing the duplicate variables and matching the order across different scopes to MRI.
