Thanks, I hadn't actually seen the reference_wrapper library before, so
didn't look too deeply (just far enough to know that passing the raw
object didn't work).

So, effectively, I'm proposing a small addition to boost::variant, in
some sense 'embedding' the boost::reference_wrapper functionality into
it, and applying a little syntactic sugar.  Does anybody see any value
in this, or is it just me?  (In the meantime, I can always use a small
wrapper to boost::variant that adds these changes.)
