Hi Jacopo - I have been interested to read the counter-arguments to my proposal to remove the keyword.

I’m also glad it helped to spark a proposal to try to refine the behavior with some kind of "reswitch" mechanism, but I don’t have any passion for pushing that particular proposal along.

My motivation in proposing to remove the fallthrough keyword was that it makes sense to be judicious about language features and keywords especially while the language is young. The feature still seems questionable to me, but if the prevailing opinion is that "fallthrough" or a similar case-jumping mechanism is worth keeping, then I respect that and will not be pushing my original proposal any further.
