+ C++11: Small uses of auto.
+
+2016-04-01 Murray Cumming <murrayc@murrayc.com>
+
+ C++11: slot: Use = default for simple copy constructor.
+
+ With help from clang-tidy, like so:
+ clang-tidy-3.8 -fix --checks=modernize-use-default --header-filter=.* `find . -name "*.cc"`

+
+ This reverts commit 798210eeaedd88477b71115423b1d7928e81138f.
+
+ Because this doesn't work with g++ (at least version 5.2.1)
+ though it does work with clang++ (3.8).
+
+ g++ gives this error:
+
+ test_tuple_start.cc: In function ‘constexpr void test_tuple_start_constexpr()’:

* @section features Features
*
* - Compile-time typesafe callbacks (also faster than run time checks)
- * - Type-safety violations report the line number correctly with template names
+ * - Type-safety violations report the line number correctly with template names
* (no tracing template failures into headers)
* - No compiler extensions or meta compilers required
* - Proper handling of dynamic objects and signals (deleted objects will not
*
* Your @c pkg_check_modules() call should also mention any other libraries that
* you need to use via pkg-config.
- *
- * @section scope Scope of Documentation
- *
- * libsigc++ contains many template functions and template classes/structs,
- * some with many specializations. This reference manual does not show all
- * specializations of those templates that hardly any user will use directly.
