extends Signal

Author:

tvc A SignalEscape signal exception is raised whenever the 'quit' function of an escape block is invoked. It causes control of the interpreter to return to the invocation of the escape block. In other words, SignalEscape 'abuses' the Java exception handling mechanism to perform a non-local return.
