        Do nothing in case 1 is indeed a good point. THERE a break could mean
something, and exactly the same as what break means in if/for/while etc.:
break out of the current block. So mandatory requiring a break doesn't do
that: it's unnecessary, however requiring a break, you could use break for
that, which is precisely why break is in the language. However the breaks in
case clauses with code... not necessary.
