[boost] serialization of variant

Hi! I was working with an older version of boost which didn't have support for serializing variants. So I started to implement serialization of variants myself. When I looked into a newer version of boost I found serialization/variant.hpp . So I compared the boost version with mine. I found that I am missing some things, but I implemented the type lookup with a plain switch instead of repeating if-statements in a recursive function. I want to contribute my switch-code to boost but I don't know whom to email my code. Frank
