'goto" gone from computer languages or is it!

  I've been programming in C since 1990, and in that time, I've only used
GOTOs under three conditions (as far as I can remember):

	1. A function with a lot of cleanup required if it fails, so I use a
	GOTO to clean up before returning an error; this is rare for me
	though.

	2. State machines.  It keeps me sane.  This is my biggest use of
	GOTOs.  My HTML parser has 22 GOTOs (22 states) and without the use
	of GOTOs, the code would probably be more of a mess than it already
	is.

	3. *VERY* rarely, as a mechanism for exceptions, and then, I use
	setjmp()/longjmp() (which are non-local GOTOs in C).  I think I
	played around with this a few times, but gave up on it (I don't
	particularly care for the semantics of setjmp() and it has some
	rather nasty restrictions on the return value).
