<<I disagree. In the loop/case method, you can put "State := Bad_State;"
at the top of the loop, and then "when Bad_State => Assert(False);" in
the case statement. With the goto solution, you have to use care on
each state, rather than once for the whole mess.>>
I disagree, I find it ugly to force you to do a state transition by
reassigning the state, when there is no state transition.
Furthermore, if you want a simple canonical way to prevent fall through,
just say
raise Program_Error; <<state-name>>
to label a state.
