Thanks! Now it is a lot more clear.

It is a very good idea. I will do it when Boost.Bimap is settled down.

Nice! That will be very useful. A map where you can iterate over
the data types? Sounds good to me. I think it will be a little tricky
to implement but I have some ideas to keep it simple. If there
is interest I put this in Boost.Bimap TODO list. ( This is not a
performance, this is the first time Joaquin tell me this idea... )

Thank you again!
