This can also be done:

 Â  using container=multi_index_container<
 Â Â Â  element,
 Â Â Â  indexed_by<
ordered_unique<keys<element,&element::x,&element::f,&gf>>
 Â Â Â  >
 Â  >;

(see http://coliru.stacked-crooked.com/a/c2b27ff9542d6651 ). The only 
annoyance
is that one has to specfiy element in keys<element,...> before the keys 
proper.
