I have a value type (Foo) which is supposed to contain references to some multi_index_container of its type, like so:

struct Foo {   int property1;   int property2; 

  FooMIC* other; // this (the pointer value) may or may not be // indexed upon

};

typedef multi_index_container< Foo,    indexed_by     < sequenced<>     , ordered_unique< member >

    , ...     >>  FooMIC;

Due to recursive nature of this, I wasn't able to figure out how do declare such a thing (other than unsafely using void* references in Foo). 

Try this: struct Foo { int property1; int property2; struct FooMIC* other; }; typedef multi_index_container< Foo, indexed_by< sequenced<>, ordered_unique> > > FooMICBase; struct FooMIC:FooMICBase { using FooMICBase::FooMICBase; }; HTH Joaquín M López Muñoz Telefónica
