A marker interface implemented by all core library exceptions.
An Exception is intended to convey information to the user about a failure, so that the error can be addressed programmatically. It is intended to be caught, and it should contain useful data fields.
Creating instances of Exception directly with Exception("message")
is discouraged in library code since it doesn't give users a precise
type they can catch. It may be reasonable to use instances of this
class in tests or during development.
For failures that are not intended to be caught, use Error and its subclasses.
