   Yeah.  Using boost::variant looks a little unwieldy, as I'd have to  
deal with results from the database as complicated boost::variants  
with at least 5 possibilities, but it would be doable with something  
as simple as a typedef, I'd guess.

   Sub-ideal, but may be a reasonable way to do it.
