I have never seen a real-world situation in which a "continue" was needed. The
vast majority of times that I've seen where people have claimed they needed it,
it could be replaced by an "if". The few remaining cases involved very
convoluted and unreadable code. When it was rethought and simplified, it no
longer needed a "continue". I would be interested in seeing real-world examples
where it was needed.
An informative data point is the book /Software Tools/, which presents a whole
lot of code in Ratfor, which has an equivalent of "continue". Interestingly, it
is never used.
