The following returns an object of whatever type bar is: we dereference bar when it's the only field requested.

bar = db.one('select foo from bar')

But what about this?

bar = db.one('select foo from bar', back_as=dict)

Right now the dereferencing trumps the back_as, but @seanlinsley, at least, expected the back_as to bind tighter. I can see that. Anyone else?
