An Internet search
https://stackoverflow.com/questions/33607284/control-reaches-end-of-non-void-function-with-fully-handled-case-switch-over-a
teaches me that it is legal to construct a value of an enum type that
is not among the enumerated values (when the number of enumerated
values is not a power of two). <sigh>
I added the fake return. I prefer not to put a default case in the
switch, so that the "switch is not exhaustive over enum" warning can
still appear.
