-/// Takes ownership and "forgets" about the value **without running its destructor**.
+/// Like [`forget`], but also accepts unsized values.

-/// This function works exactly the same as [`forget`], except it also accepts unsized values. It
-/// will never be stabilized and is only available because we haven't decided to relax the bounds
-/// on [`forget`] just yet.
+/// This function is just a shim intended to be removed when the `unsized_locals` feature gets
+/// stabilized.
