[Boost-users] [boost-users][multi-index] passing modifier by reference/pointer?

Hello,

Is there a simple way to pass a modifier by reference/pointer in the
following expression:

my_multi_index_container.modify(somePos, modifier);

"modifier" is a functor that has some internal state, so I wouldn't
like it to be copied.
Is it possible to do this without an explicit creation of a binder
that binds operator() and &modifier (or so)?

Thanks.
