[Boost-users] Containers question

Fellow boost enthusiasts, I want to be able to store a set of information that contains types. For example:

template<typename T> void register_field( const FieldID id ) { // need to keep a record of (T,id) }

Later on, I need to recover the type and id (T,id) for use. Any thoughts on a way to accomplish this? Thanks for any advice, James
