+ * @func

+ * @since v0.9.0
+ * @category Object
+ * @sig {s: x} -> {x: [ s, ... ]}
+ * @param {Object} obj The object or array to invert
+ * @return {Object} out A new object with keys in an array.
+ * @see R.invertObj
+ * @example
+ *
+ *      const raceResultsByFirstName = {
+ *        first: 'alice',
+ *        second: 'jake',
