So, from my perspective, if we just adopt a style rule for Google Style that when using switch in an expression context one should stick to `->`, I might have basically what I want.

I agree it makes sense to aim for this as an "extra clean" notation,
not a separate design but a subset of the whole design.

It's a motivator for the design of multiple labels for one switch chunk
(the nice kind of fallthrough).  So "case 1,2,3" syntax is a tweak for
"case 1: case 2: case 3", allowing either colon or arrow after the
third case label.
