Then I find the word "ignore others" misleading. Quite the
contrary, the user has to be aware of the others and not to give
them.
Define an "operating mode" option, only one of which in the
same group of "operating mode" options that share the same
`int_var` can be given by the user. `enum_val` is set to
`int_var` when the option is used, but an error is reported
if other "operating mode" option has already set its value
to the same `int_var`.
or something?
