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:
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.
