I beg to differ. "Never, never, never use goto!" is one of those programming mantras which are taught to beginners because at that level, the temptation is to use it where it is not appropriate. However, as a developer becomes more experienced, the usefulness, clarity, and simplicity of an unencumbered "jump over there" instruction make it more valuable when used sparingly and appropriately. And in this case, an exception handler of a sort that basically says "go back three lines and try it again," the use is very appropriate.

While we are drifing dangerously offtopic, I am going to ask you to reconsider the two snippets above, and tell me which is actually more readable -- the one that obfuscates a goto with a while loop, or the one that explicity uses the goto when the goto is EXACTLY the instruction being used in both, algorithmically.
