[boost] [variant]anyone working on variadic template version?

Is anyone working on a variadic template version of variant, i.e.
one that defined as:

   template<typename... T>class variant;

instead of:

   template
   < typename T0  = detail::variant::void_
   , typename T1  = detail::variant::void_
   ...
   , typename T19 = detail::variant::void_
   > class variant;

?

I'm thinking of attempting that, but I'd hate to waste
time if someone else has already done it or made some
progress on it.  Although BoostCon09 did have a workshop
on CXX0x:

   http://www.boostcon.com/community/wiki/show/Start/HandsOnCXX0x/

the sandbox directory for that:

   https://svn.boost.org/svn/boost/sandbox/boost0x

didn't appear to use the variadic template feature in variant:

TIA.
