+========================================
+
+Warns on default lambda captures (e.g. ``[&](){ ... }``, ``[=](){ ... }``).
+  
+Captures can lead to subtle bugs including dangling references and unnecessary
+copies. Writing out the name of the variables being captured reminds programmers
+and reviewers to know what is being captured.

"reminds [...] to know" sounds a bit unnatural to me, maybe:
```suggestion
and reviewers about what is being captured.
```
