| It seems the -O2 option can give a significant speed increase relative
| to just the -O option. This is contrary to the documentation which says
-O2 switches on SpecConstr, which has improved quite a bit in the last year or so. There's a paper on my home page about it ("Constructor specialization for Haskell").
Perhaps we should review the documentation you point to!
