Hmm... for me, when use fall-through, need 2 things:
- need a comment.
- next case need not notice about prev case which fall-through.
If we can not fit the 2 things above, either can not use sub functions
or macros for it because of performance reason, 'goto' is better than
'fall-through'.
For me, in most cases, when a function becomes a long function, it is
always better to use sub-fuctions or macros instead of some blocks (but
it is really not urgent :-) ).
Thanks.
