Support returning object partials from select

[evanrs]

Select, or some new method should support return object partials, like lodash pick.

One implementation could be

    select(key, __, ...args) {
      return (
        // A list of arguments > 3 returns those values as an array        
        // args.length ?
        //   [key, __, ...args].map((arg) =>
        //     isArray(arg) ? selector(...arg) : selector(arg)) :

        // Two array of values to select and defaults
        isArray(key) && isArray(__) ?
          map(key, (key, idx) => selector(key, __[idx])) :

        // A object that is a mapping of `{ [key]: [default] }`
        isObject(key) ?
          mapValues(key, (__, key) => selector(key, __)) :

        // Default behavior
        selector(...arguments)
      )
    }
