Also, if it is true that this is a "non-starter", I would assume it is also
a non-starter to only allow single expressions in the conditional operator
`?:`. If not, what is the fundamental difference?
We normally don't get to embed statements inside expressions, except in the
case of anonymous classes and lambdas, where we (a) they must be set off
with curly braces, and (b) they are only embedded physically, and don't
immediately execute. If we do this for switch, we should at least stick
with (a), but (b) is a thing with no precedent. It seems reasonable that we
should require some very solid motivation before breaking that precedent.
