Comment (by lightandlight):

 My use case is that I have a large datatype, where some of the fields are
 datatypes that contain abstract datatypes (these abstract datatypes are
 declared in a signature in another package). I want to use TH to generate
 lenses for the large indefinite datatype.

 Also, should we take this particular discussion off the tracker?
