But in this example the code between do_normal_stuff and 
end_normal_stuff would never be executed, not even in C!

Why not write something simpler

case num
 when 1:
  if 0 <= var and var <= 10) then
    do_normal_stuff
    ...
    ...
    end_normal_stuff
    puts "Write it"
  end


I think you are trying to be too clever here. Stick to the simple stuff.
