Originally, Smalltalk used an instance based exception handling scheme, where instances of Signal where created and raised. Now, all implementations have moved to class based exceptions, where the raised exception is a subclass of Exception. As instance based exception handling is still useful in some situations (very lightweight, no need to create a class), some dialects continue to support both.
