If only I knew about it before coding it by hand. It anyway it wasn't
that bad cause I only support a subset of the AST and my hand-made
Lift instance serves as well to cut detect unused branches.

I wonder if there is any work being done to port DriFT to TH. It would
be great, cause it wouldn't require using an external tool anymore and
the affected Haskell code wouldn't need to be preprocessed.
