I totally agree. What I'm saying is that providing patches with features
request should be *encouraged*, not *required* (and certainly not
discouraged! :).

Sure, he might be able to change his patch in a way that has consensus.

Well, you only have to write "goto case;", no need for the label if you
only want fall-through.

It's really sad that Walter dismissed this issue, even when nobody else
defended the implicit fall-through and even he was proved wrong about his
own frequency of use.


Come on, Walter! =)
