Currently this will actually find many duplicate nodes. I will fix these issues in separate PRs after this has been merged. |

There was a problem hiding this comment.
mypy doesn't like this because it doesn't know about the type.
What's the reason for doing this based on the name of the type instead of the type?

…ython#4647) It's hard to manually ensure that all relevant nodes are merged in AST merge and that no references to stale objects remain. This automated opt-in check looks for these duplicate nodes. It can be enabled in tests by switching `mypy.test.testfinegrained.CHECK_CONSISTENCY` to True. This was originally implemented by @msullivan. I did various minor changes and some refactoring.
