CLASS	Exception @public	The base class for all exceptions.
CLASS	Exit @public	Exception thrown by EXIT.
CLASS	Interrupt @public	Exception thrown by a user interrupt: CTRL-C pressed or signal SIGHUP or SIGINT received.
CLASS	TimeOut @public	Exception thrown when a timer expires.
CLASS	Error @public	Base class for exceptions that are an error.
CLASS	OutOfMemory @public	Exception thrown when out of memory.
CLASS	NilAccess @public	Exception thrown when dereferencing a NIL.
CLASS	MemoryAccess @public	Exception thrown when accessing memory that cannot be accessed.
CLASS	Init @public	Exception thrown when initialization failed.
CLASS	Check @public	Exception thrown by a method in the CHECK module.
CLASS	Unsupported @public	Exception thrown when code is not implemented.
CLASS	BadValue @public	Class of exceptions that are thrown when a value is unacceptable.
CLASS	OutOfRange @public	Exception thrown when an index is out of range: idx < 0 idx >= Size()
CLASS	KeyNotFound @public	Exception thrown when making a dict loopup for a key that does not exist.
CLASS	ItemNotFound @public	Exception thrown when searching for an item in a container that does not exist.
CLASS	KeyExists @public	Exception thrown when adding an item to a dict for a key that already exist.
CLASS	IllegalByte @public	Exception thrown when encountering an illegal byte in a UTF-8 string.
CLASS	Arithmetic @public	Exception thrown for a non-specific Arithmetic error
CLASS	DivideByZero @public	Exception thrown when dividing by zero.
CLASS	Overflow @public	Exception thrown for a value overflow.
CLASS	IOError @public	Exception thrown for a non-specific I/O error
CLASS	FileNotFound @public	Exception thrown when a file cannot be opened because it, or its directory, cannot be found.
CLASS	AccessDenied @public	Exception thrown when a file cannot be opened for the current user and the requested operation.
CLASS	Pipe @public	Exception thrown when writing to or reading from a pipe that is not open.
CLASS	Dyn @public	Exception thrown when using a dyn type.
CLASS	WrongType @public	Exception thrown when a type is used where another type is expected and automatic conversion is not possible.
CLASS	Thread @public	Exception thrown when an operation on a thread fails.
CLASS	Internal @public	Exception thrown when running into an internal error. Sorry!

	unhandledException(e) @file
	reportStack(writer) @public	Write the current stack backtrace to writer.

members (alphabetically)

PROC reportStack(IO.I_Writer writer) @public

Write the current stack backtrace to writer.

PROC unhandledException(E.Exception e) @file

When an exception is thrown while in here do not call beforeExit() again. Otherwise a SEGV in beforeExit() will loop forever.
