Certainly, you can find the proof of concept implementation I used for 
the tests here: http://fusionfenix.com/ktests/boost.fusion.map.zip
It is intended to be used with Boost.Fusion from trunk, you just need to 
replace fusion's "map" directory with the "map_" one in the zip.

Keep in mind that it is just a proof of concept. I am working on a full 
fledged implementation as time permits, which is not as often as I would 
like.
