I expect it's there mostly because of consistency. Other than in JAPHs, I've never used a continue on a bare block - but then, I can't remember the last time I used a continue on a while or foreach block.

But I do like bare blocks. Sometimes I find it more convenient to write {...; redo; ...} than while (1) {...; last; ...}. It'll depend on the use of last/next/redo.
