I'm trying to use boost::multi_index for the first time, and I'm
getting odd compile errors.
I have a class with two "keys", a text one and a numeric one, and I
want to have two indices
into the collection.

So, I tried several things, and all of them get the same error:
'index_class' is not a member of class
        (and then an amazing cascade after that)

Here's the basic idea:

typedef boost::multi_index_container <
        boost::multi_index::indexed_by <

        boost::multi_index::ordered_unique <
boost::multi_index::identity < Foo >, LessThanNumeric >,
        boost::multi_index::ordered_unique <
boost::multi_index::identity < Foo >, LessThanText >
> Foo_;

where LessThanNumeric (and LessThanText, too) looks like this:

        struct LessThanNumeric: std::binary_function< Foo, Foo, bool > {
                bool operator () ( const Foo& x, const Foo& y ) const {
                        return x.NumericKey () < y.NumericKey ();

Anyone got any tips?
