What happens if you assign a new value to <variable> inside a case block and dont use break? What value become checked in the next case test? the new assigned one or the local remembred one?

   else                 -- optional else block if no case conditions matched
     <block>            -- if last statement in else is a break it will be
end                    -- optimised out and will not appear in the bytecode
