+1
To me continue clauses are like goto statements. I try to avoid them whenever
possible. Only in some extreme cases where I would get like 12-times indented
code, then its better than else...
When reading some code long afterwards, it's quite easy to miss a continue or
return (the two pathes of an if are indented and thus easy to spot) and then
wonder why some statement apparently has no effect.
Cheers,
Reinhold
