Comment (by dfeuer):

 zaoqi, you should look at [https://hackage.haskell.org/package/logict
 LogicT] for an example of the continuation-passing style (CPS) approach.
 But please note that that approach also has severe efficiency problems in
 some cases. For a solution that's never very fast but also never terribly
 slow, read the paper called "Reflection Without Remorse".
