Hi Emil, Your problem is related to "how are things evaluated" not "when". The short answer is: if you want to make sure an expression is evaluated before you lift it, don't use quasiquotes, call Language.Haskell.TH.lift

Therefore [| y |] is equivalent to "lift y" > z = (2::Int) + 2 > > a4 = [| z |] z is a global variable and [| z |] is lifted to a variable expression (i.e. a4 is equivalent to "varE 'z" ) _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
