+==================================
+
+Warns on default lambda captures (e.g. ``[&](){ ... }``, ``[=](){ ... }``)
+  
+Default captures can lead to subtle bugs including dangling references with
+``[&]``, unnecessary copies with ``[=]``, and make code less maintainable by
+hiding which variables are actually being captured.
+
+Implements Item 31 of Effective Modern C++ by Scott Meyers.
