/**
 * Creates a new object with the own properties of the two provided objects.
 * If a key exists in both objects:
 * - and both associated values are also objects then the values will be
 *   recursively merged.
 * - otherwise the provided function is applied to the key and associated values
 *   using the resulting value as the new value associated with the key.
 * If a key only exists in one object, the value will be associated with the key
 * of the resulting object.
