This would indeed be nice, because I catch myself making this error also often. Somehow the do seems superfluent. But I don't think it would be possible to detect this always, because the | are parsed as bitwise or's, so there is only a superfluous end. The proposed indentation heuristic would give a correct result. So the missing end patch would help here.

(If I remember the thread correctly)
