That's where *proxy* comes in. You create an empty table that redirects
to the db handle. Something like this:

function db_proxy(db)
 local m= {
	__index=function (t,k) return db:get(k) end,
	__newindex=function (t,k,v) db:set(k,v) end
	}
 return setmetatable({},m)
end

You can also add __pairs calling db:cursor, etc.
