Polymorphic return values are really useful. Often, we just want to
|
|
know if something worked or not. Other times, we'd like to know what
|
|
the error text was. Still others, we may want to know what the error
|
|
code was, and what the error properties were. We don't want to handle
|
|
objects or data structures for every single return value, but we do want
|
|
to check error conditions in our code because that's what good
|
|
programmers do.
