`let f: T; f = (n) => ... f(n - 1)` at module scope threw "Cannot access 'f' before initialization": a function-typed (pointer-guarded) binding kept the null-pointer TDZ test on its writes, but the declaration already initialized it (to undefined) when it ran. Such bindings now carry the existing initialization flag: the declaration sets it, writes that can run earlier check it, and writes no longer test the empty pointer. A write that really precedes the declaration still throws. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
