This makes mypy raise an error whenever it detects code which is
statically unreachable, e.g.
x: int
if isinstance(x, str):
... # Statement is unreachable [unreachable]
This is really neat and finds quite a few logic and typing bugs.
Sometimes the code is intentionally unreachable in terms of types, e.g.
raising TypeError when a function is given an argument with a wrong
type. In these cases a `type: ignore[unreachable]` is needed, but I
think it's a nice code hint.

Without the patch the test fails as follows:
# Prepending should call fixup_namespace_packages.
monkeypatch.syspath_prepend("world")
> import ns_pkg.world
E ModuleNotFoundError: No module named 'ns_pkg.world'
