[Boost-users] [tuples, multi-index] tuples::get as key extractor

Hello, Consider the following types: typedef tuple Item; typedef multi_index_container< Item, indexed_by< ordered_non_unique > >

Items;

The above types don't compile (MSVC10) because of &tuples::get<1>: C2440: 'specialization' : cannot convert from 'overloaded-function' to 'int (__cdecl *)(boost::tuples::tuple &)' It seems there're several overloaded function templates "tuples::get"... So, what's the correct type of the appropriate function? Or -- is there a more "robust" way to extract the key (without defining explicit function-object)? Thanks!
