I've got a feature request about list_of and vector_of. When writing for instance:

bimap<set_of<X>,list_of<Y> >

we know (unlike in Boost.MultiIndex) that the Y part does not belong to any index key and thus can be freely mutated. Could it be possible that, in those cases, the associated relation class held a mutable Y allowing for direct manipulation of that member?

Nice! That will be very useful. A map where you can iterate over the data types? [...]

Not sure if I've explaiend myself clearly. What I mean is, suppose I've got typedef bimap<set_of<int>,list_of<std::string> > bm_type; then it'd be good to be able to write: bm_type bm; ... bm.left.begin()->second="hola"; which is currently not possible since bm_type::value_type::left is const. But in this particular case there's no danger in making bm_type::value_type::left a mutable member (thus allowing for the above) since list_of<> is not key-based. Sorry if my proposal was already clear and this re-explanation is superfluous, but I'm not getting yout "you can iterate over the data types" part.
