+Since I apparently forgot to post a blog post last week, this blog
+post covers two lang-team triage meetings: [2019-11-14] and
+[2019-11-21]. Recordings from [both] [meetings] are also available.

+## Updates on shepherded items
+
+Here is a list of the ["shepherded items"] that the lang team is
+tracking, along with weekly updates on the latest developments.
+
+["shepherded items"]: http://smallcultfollowing.com/babysteps/blog/2019/09/11/aic-shepherds-3-0/
+
+* [const-eval](https://github.com/rust-lang/const-eval)
+    - there is progress towards extending the set of expressions
+      permitted in constants to include `&mut` borrows, if/match, and
+      loops.
+* [project-ffi-unwind](https://github.com/rust-lang/project-ffi-unwind)
+    - current status: currently evaluating whether "C" functions should 
+      permit unwinding by default
+    - trying to get measurements of the impact on code size
+    - prototyped the plan in a rustc branch, but needs a few updates and to be executed
+      on a representative code base (likely Fuschia)
+* [Coherence can be bypassed by an indirect impl for a trait object](https://github.com/rust-lang/rust/issues/57893)
+    - did a [crater run of the proposal](https://github.com/rust-lang/rust/pull/66037#issuecomment-549575983) but have only partially analyzed the impact
+* grammar working group — qmx
+    - no updates this week
+* `!` type and fallback — centril
+    * [`!` is stable on nightly!](https://play.rust-lang.org/?version=nightly&mode=debug&edition=2018&gist=a16420f41bbd2496ed07c75cf048189e)
