[boost] [fusion] variant adapter going away

Hi,

I intend to remove the variant adapter from fusion. After thorough
investigation, I think now that the move to make variant a
fusion sequence is rather quirky. A variant will always
have a size==1 regardless of the number of types it can contain
and there's no way to know at compile time what it contains.
Iterating over its types is simply wrong. All these imply that
the variant is *not* a fusion sequence.

If there are objections, I'd like to hear them.

Regards,
