See no more type errors in your IDE.
Additionally, try some workflows and see no regressions:
- arc anoid: still works (yeeeh)
- arc browse: still works e.g.
- `arc browse ./src/workflow/ArcanistWorkflow.php:4`
- https://we.phorge.it/source/arcanist/browse/master/src/workflow/ArcanistWorkflow.php$4
- `arc browse --branch stable ./src/workflow/ArcanistWorkflow.php:4`
- https://we.phorge.it/source/arcanist/browse/stable/src/workflow/ArcanistWorkflow.php$4
- arc look: still works "You stand in the middle of the forest"
- arc look remotes: still works: "At the far edge of the grove, you see remotes: origin"
- arc shell: still works, your ~/profile is updated
- arc lint: introduce a tab somewhere, still works
- arc unit: still works; plus, break a unit test assertion (e.g. in ./src/__tests__/PhutilLibraryTestCase.php), the error is still reported
- arc patch: still works; e.g. on top of this patch you run `arc patch D26041` and it still works
- arc land: we haven't tested this specific point but the author of this patch will land this patch sooner or later :^)
