Comment (by simonpj):

 >  I have another plan: I will introduce a new data GenStgFreeVar occ =
 StgFreeVar occ [occ] type and calculate the sharing in CoreToStg as we
 have all the relevant data available and in good shape anyway.

 I think that's a great plan: see [wiki:NestedClosures] under
 "Implementation".

 If you could describe the moving parts of your plan in the wiki page, it'd
 help us to offer you support and feedback.
