+========================================
+
+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. And knowing is half the battle.
+
+Coding guidelines that recommend against defaulted lambda captures include:
+
+* Item 31 of Effective Modern C++ by Scott Meyers
+* `AUTOSAR C++ Rule A5-1-2 <https://www.mathworks.com/help//releases/
