What, C doesn't have tuples yet ? <g>

I program in C++. Personally I have left C far behind. Bjarne and Linus 
not withstanding, I think C++ as a language should be less backward 
accomodating to C and move forward on its own more.

I do understand that PODs are still attractive as data types. Therefore 
I think that magic_get would be a nice addition to Boost.
