+/**
+ * Idiom useful for test programs: catch an expected exception, store its
+ * what() string in a specified std::string variable. From there the caller
+ * can do things like:
+ * @code
+ * ensure("expected exception not thrown", ! string.empty());
+ * @endcode
+ * or
+ * @code
+ * ensure_contains("exception doesn't mention blah", string, "blah");
+ * @endcode
+ * etc.
+ *
+ * The trouble is that when linking to a dynamic libllcommon.so on Linux, we
+ * generally fail to catch the specific exception. Oddly, we can catch it as
+ * std::runtime_error and validate its typeid().name(), so we do -- but that's
+ * a lot of boilerplate per test. Encapsulate with this macro. Usage:
+ *
+ * @code
+ * std::string threw;
+ * try
+ * {
+ * some_call_that_should_throw_Foo();
+ * }
+ * CATCH_AND_STORE_WHAT_IN(threw, Foo)
+ * ensure("some_call_that_should_throw_Foo() didn't throw", ! threw.empty());
+ * @endcode
