I created a library, called cxx_dual ( cxxd for short ) at 
https://github.com/eldiener/cxx_dual, to solve the above problem for 
library developers or for end-users in their own program code. But for 
various reasons this library was not popular with other Boost 
developers. Feel free to look at it and to post questions, bug reports, 
or suggestions about it. The library also exists in the Boost Library 
Incubator.
