 Review comment:
   I get this error: [Decorated property not supported](https://github.com/python/mypy/issues/1362).
   
   The typechecker has a problem with decorated properties for some reason, and the typechecker
only gets run on the file if there is at least one type hint used or something from `typing`
is imported. So, what changed is that there is now typing in this file.
