Extension of std::exception objects with a member @a id for exception ids. Extension of std::exception objects with a member @a id for exception ids.
@note To have nothrow-copy-constructible exceptions, we internally use
std::runtime_error which can cope with arbitrary-length error messages.
Intermediate strings are built with static functions and then passed to
the actual constructor.
