I believe the text book example is a language that lacks support for 
something like Java's "finally" block.  A goto can guarantee you get to 
the code that must be executed, no matter the outcome of the current block.

One example of a legitimate use of goto from perlsub:

  Many "AUTOLOAD" routines load in a definition for the
  requested subroutine using eval(), then execute that sub-
  routine using a special form of goto() that erases the
  stack frame of the "AUTOLOAD" routine without a trace.
  (See the source to the standard module documented in
  AutoLoader, for example.)
