I think this is going to generate some warnings in the various static
analysers as they will point out there are lots of values channel can
take that aren't handled by the switch statement.. You should have
a default.
(This is what made Dan less than convinced of whether this was a good
change when I originally suggested it) I still think it's a marginal
improvement in making it explicit that we only have two valid choices
though - and Dan didn't care strongly about it.
