Subject: RE: Change in "goto" behavior
Dijkstra should have titled his letter "Stupid
programmers considered harmful". A good programmer will
write good code no matter how liberal the language, and
a bad programmer will write bad code no matter how
restrictive the language.
Since someone asked, there's one situation where goto's
are the best answer, even in fully structured
languages: When you need to use a multitude of deeply
and unevenly nested blocks to determine if some complex
situation obtains, and there are several points in the
nests at which the answer is determined. From each of
those points you goto some code which does its thing
and then exits, never trying to re-enter the nest. The
alternative to goto in this one case is artificially
contrived blocks that amount to structure for structure's sake.
That's just an elaboratiuon of what $Bill said. Now
can we end this
religious discussion?
