- the NamedEnum wrapper is somewhate too rigid.
* All enumerated values are contiguous, starting as zero.
* The implicit one-to-one mapping precludes using it for aliases.
* For example, perhaps we want to support alternative lookup names for an
enumeration, or manage an enumeration lookup for a sub-range.
