// be built by many different targets with their own compiler options.
// In particular, this will allow a safe way to throw exceptions even if the
// caller is compiled with -fno-exceptions. This is intended for implementing
// things like map<>::at(), which the standard documents as throwing an
// exception on error.
//
// Using other techniques like #if tricks could lead to ODR violations.
//
// You shouldn't use it unless you're writing code that you know will be built
// both with and without exceptions and you need to conform to an interface
// that uses exceptions.
