[Boost-users] [multi_index] recursive declaration of MIC with a value which contains references of its kind

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). Any ideas? Thanks many, Nick
