/** @defgroup exception_catch exception_catch()
* sigc::exception_catch() catches an exception thrown from within
* the wrapped functor and directs it to a catcher functor.
* This catcher can then rethrow the exception and catch it with the proper type.
*
* Note that the catcher is expected to return the same type
* as the wrapped functor so that normal flow can continue.
*
* Catchers can be cascaded to catch multiple types because uncaught
* rethrown exceptions proceed to the next catcher adaptor.
*
* @par Examples:
* @code
* struct my_catch
* {
* int operator()()
* {
* try { throw; }
* catch (std::range_error e) // catch what types we know
* { std::cerr << "caught " << e.what() << std::endl; }
* return 1;
* }
* }
* int foo(); // throws std::range_error
* sigc::exception_catch(&foo, my_catch())();
* @endcode
*
* The functor sigc::execption_catch() returns can be passed into
* sigc::signal::connect() directly.
*
* @par Example:
* @code
* sigc::signal<int> some_signal;
* some_signal.connect(sigc::exception_catch(&foo, my_catch));
* @endcode
*
* @ingroup adaptors
