Create reflexsive enumerations out of JavaScript objects.
const assert = require('assert')
const { enumFactory } = require('enum-nom-nommer')
const s = (object) => JSON.stringify(object, null, ' ')
Numeric enums
// A log level object with "weighted" values

debug: 5,
error: 0,

info: 2,

6: 'silly',
