* [ ] **Close issue** [#5418](https://github.com/dotnet/fsharp/issues/5418): confirmed fixed (PR #19504 merged 2026-04-11), existing test coverage in WarnExpressionTests.fs — [View comment](https://github.com/dotnet/fsharp/issues/5418#issuecomment-4252432195)
* [ ] **Review PR** [#19947](https://github.com/dotnet/fsharp/pull/19947): Community fix for #4161 (FS0410 spurious accessibility error on tuple-destructured bindings in private modules) — has merge conflicts, needs resolution + reviewer approval — [Review](https://github.com/dotnet/fsharp/pull/19947)

## Additional observations for maintainer's attention

* Issue [#16292](https://github.com/dotnet/fsharp/issues/16292): **Debug-only codegen bug** — SRTP with mutable struct enumerator causes infinite loop in Debug builds.
* Issue [#11929](https://github.com/dotnet/fsharp/issues/11929): Calling protected static base member from `static do` — confirmed still reproduces without `--realsig+`, and IS fixed with `--realsig+`. Will resolve naturally when `--realsig+` becomes the default.
* Issue [#4161](https://github.com/dotnet/fsharp/issues/4161): Community contributor `@KirtiRamchandani` opened PR [#19947](https://github.com/dotnet/fsharp/pull/19947) fixing the spurious FS0410 for compiler-generated `patternInput` bindings in private modules. PR has merge conflicts (since 2026-06-24).
