   Yes, but I thought I read that we always had to explicitely 
specify one ending statement, as "goto", "continue"... or 
"break"; which, in many basic cases, means having to add "break" 
at the end of each case. One motivation was to force to make it 
look like C (I cannot say I agree with this purpose, but I think 
I read it somewhere).

   I was talking about my problem with the mailing-lists (the one 
in my "PS"); I am not sure you are talking about it.
