Hi
As for the specific issue of whether we should turn on -fstrictness with -O0, I suspect the answer is that the compile-time cost would be too high.
There would also be the issue that it would increase the amount of Haskell code which works only in GHC, which is probably a bad thing. Would the strictness still recover the loop if they turned on hpc/profiling? I can see many reasons why making things faster is good, but making things asymptotically faster/less space in -O0 could bite later. One ticket that probably makes a big difference in -O0 is: http://hackage.haskell.org/trac/ghc/ticket/2207 Thanks Neil
