Warning

W1007 — Implicit type widening in as cast

No example yet

No fixture in the test suite asserts this code, so there is no program here that is known to trigger it. That is a gap in our coverage rather than a statement about the code.

Contributing one is a good first change — add a fixture under tests/ with a CHECK line naming W1007, and this page picks it up.
