The emphasis in this tutorial has been on library development; but Objections
can be used for any third-party software.
They can be added quickly to software
to implement a simple, robust method for handling errors.
They do not behave like
exceptions, and will not migrate invisibly to formal exception handling.
of the language
today can implement error handling in a way which will guarantee
to migrate naturally to exception handling.
At least Objections are simple enough
that not much will have to be undone when exceptions are finally in use.
